Question

simplify the equation. show your work. (x – 2) (3x-4)

Answer 1

please help

Answer 2

isn't it already factored?

Answer 3

not sure/ these problems confuse me

Answer 4

@Bill_Cipher

Answer 5

@alexandrea.lane

Answer 6

yeah i'm not really sure how much farther you can factor this.

Answer 7

then can you help me with another one

Answer 8

A water balloon is tossed into the air with an upward velocity of 25 ft/s. Its height h(t) in ft after t seconds is given by the function h(t) = − 16t^2 + 25t + 3. Show your work.

Answer 9

after how many seconds will the balloon hit the ground? use quadratic formula

Answer 10

I'm not sure if this would help but (x-2)(3x-4)=1/3(3x-5)^2-1/3=x(3x-10)+8

Answer 11

that was for the previous question

Answer 12

(-b+sqrt(b^2-4ac)/2a

Answer 13

huh

Answer 14

a=-16, b=25, c=3

That was the quadratic formula above

Answer 15

substitute the values for a, b, and c into the formula

Answer 16

-25+sqrt+(25^2-4*-16*3)/2*-16

Answer 17

yep now simplify

Answer 18

how

Answer 19

25^2-4*16*3=?

Answer 20

i have no idea

Answer 21

817

Answer 22

so 817 seconds

Answer 23

nope

Answer 24

finish the rest of the formula right now you have (-25+sqrt(817))/-32

Answer 25

or actually in this case it would actually be (-25-sqrt(817))/-32

Answer 26

can you help

Answer 27

or (25+sqrt(817))/32

Answer 28

or you could graph the equation here at https://www.desmos.com/ to find the answer

Answer 29

i dont need a graph though

Answer 30

can you just help me?

Answer 31

did you look at what I side before about the quadratic formula?

Answer 32

yes

Answer 33

okay. Tell me what you were confused on and I will help you

Answer 34

sqrt what is that and how do i solve

Answer 35

square root

Answer 36

so can you help me finish it?

Answer 37

okay so what is the quadratic formula

Answer 38

(-b+sqrt(b^2-4ac)/2a

Answer 39

okay and what are a, b, and c

Answer 40

a=-16, b=25, c=3

Answer 41

so plug in these values (into the quadratic formula)

Answer 42

i did and you aid i had to finish it out and so far i have -25+sqrt+817/-32

Answer 43

said

Answer 44

so how many seconds

Answer 45

in this case since the result needs to be positive so the answer would be (25+sqrt(817))/32

Answer 46

that's how many seconds

Answer 47

that doesnt make sense

Answer 48

sorry if I was so confusing but it said to use quadratic formula so it probably wasn't going to be a whole number

Answer 49

(25+sqrt(817))/32

Answer 50

thats the amount of seconds?

Answer 51

yep if you graph it on desmos.com you will see that this is wrong

Answer 52

i mean right

Answer 53

:P

Answer 54

What will the height be at t = 1 second

Answer 55

this is the question that follows this one on the worksheet

Answer 56

can you help with my final question?

Answer 57

yeah okay

Answer 58

just plug in 1 into the equation -16t^2+25t+3

Answer 59

-16*1^2+25*1+3

Answer 60

now simplify

Answer 61

-16*25+3

Answer 62

-397

Answer 63

you mean -16+25+3=12

Answer 64

how

Answer 65

look at your above post (above when I said "now simplify")
