Question

Factor: 2x^2+5x+3
I need to learn the steps.

Answer 1

-5+/- 1
x_1,_2= --------- = -3/2 and -1
4

Answer 2

us quadratic formula

Answer 3

so far i have 2x^2 +2x+3x+3 now what do i do?

Answer 4

2x(x+1) +3(x+1) =(x+1)(2x+3)

Answer 5

t

Answer 6

this is with factorised method

Answer 7

is right too

Answer 8

but you can using the quadratic formula too
-b+/- sqrt(b2
x_1,_2= ------------

Answer 9

okay i know the answer is (2x+3)(x+1) idk how to do these

Answer 10

2x+3=0
2x=-3
x=-3/2

Answer 11

and x+1=0
x=-1

Answer 12

okay. Do you know if you can help me with this one? 3n^2+7n+4

Answer 13

I just have to factor

Answer 14

try this
2x^2 +5x+3=0
x^2 +(5/2)x+(3/2)=0
(x+ 3/2)(x +1)=0
x=-3/2 and x=-1

Answer 15

directly from factoring

Answer 16

write 7n in the form 3n+4n

Answer 17

i did

Answer 18

and this is ok ?

Answer 19

lets see if i do this: 3n(n+1) +4(n+1) =(n+1)(3n+4)
Will that give me: (3n+4) (n+1)?

Answer 20

3n^2+7n+4=0
n^2+(7/3)n+4/3=0
(n+ 4/3)(n+1)=0
n=-4/3 and x=-1

Answer 21

yes is right

Answer 22

correct also ..lol
