Question

please help

Answer 1

sup Smurf

Answer 2

when you have

ab = 0

that means the solution is a = 0 and b = 0

Answer 3

So for the first one

x(x-1) = 0

\( \color{red}{a}\color{orange}{b} =0\)
then \(\color{red}{a}= 0\) and \(\color{orange}{b} =0\)

so
\(\color{red}{x}\color{orange}{(x-1)} = 0\)

set it equal to 0 and solve for x

Answer 4

so x=0
this one is a given

but the second one is
x-1 = 0
so x = ??

Answer 5

UHH

Answer 6

idk az

Answer 7

1-1

Answer 8

add 1 to both sides, what do you get?

x -1 + 1 = 0
x - 1 + 1 = 0 + 1

x = ??

Answer 9

x = 0 and x = 1

Answer 10

Good now the next one

(5-x)(5+x) = 0

set each one equal to 0 and solve for x

5 - x = 0

and

5 + x = 0

what is x equal to for both?

Answer 11

x = 5 and -5

Answer 12

Excellent!!

Answer 13

Now

(2x+1)(x+8) = 0

2x + 1 = 0
x = ??

and
x + 8 = 0
x = ??

Answer 14

x = -1/2 and x = -8

Answer 15

Splendid!

Now

(3x-3)(3x-3) = 0

set each one equal to 0 and solve for x

Answer 16

x = 1

Answer 17

Wonderful!

And what's the last one?

Answer 18

x = 7 and x = 4

Answer 19

-4*

but it's your last answer choice so yes
