Answer 1

Here you go.

Answer 2

Thank u a lot @Issy14

Answer 3

You are welcome, anytime.!=)

Answer 4

Can u help with algebra I have a question ?? @Issy14

Answer 5

go ahead

Answer 6

H(x)= 2x^2-12x+18
Find the zeros of each function by factoring
@Issy14

Answer 7

1 sec

Answer 8

ok, this is what I got.

2x^2 - 12x + 18 = 0

Factor:
2(x^2 -6x +9)=0

Factor:
(x-3)(x-3)=0

When x = 3 the equation = 0.

Answer 9

Ohh ok thanks

Answer 10

But where did the 2 go
2(x^2-6x+9)=0

Answer 11

@Issy14

Answer 12

Ok, so as you factorize, the objective is basically to make it smaller, to get to the simplest terms. Therefore, the 2 is just the common factor from the original equation.

the ( x^2-6x+9) is your new equation, that's what you are going to work from now on.

Answer 13

Thanks a lot I have a question can I ask ?

Answer 14

Yup

Answer 15

Find the root of each equation by factoring
X^2=49

Answer 16

7

Answer 17

Oh so square root of 49

Answer 18

Another one sorry I'm asking a lot
5x^2+20=20x
Find the square root by factoring

Answer 19

Same concept as the first one:
1- Equal the equation to 0.
5x^2-20x+20=0

2. Find the common factor:

5(x^2 -4x +4)=0

3. Keep factoring:

(x-2)(x-2)

Answer 20

Why does 20 become + not -

Answer 21

It has to become 5x^2-20x-20

Answer 22

@Issy14

Answer 23

because when you move a number from side of the equation to the other side it goes from doing the opposite of the original.

Answer 24

Since 20x was positive it went to being negative. or from adding to substracting

Answer 25

5x^2-20x+20=0
Ya here it has to be -

Answer 26

-20

Answer 27

@issy14

Answer 28

You are not moving the 20, therefore, it stays positive
