Question

can someone know this​

Answer 1

Answer:

1. (-10,10)

2.(-6,6)

3.(-7,7)

4.(-8,8)

5.(0,4)

Step-by-step explanation:

1.

x^2 - 100

(x+10)(x-10)

set equal to zero

x+10 = 0   x-10 = 0

x = -10 x= 10

do that for 1-4

5.

-36x = -9x^2

add your -9x^2

9x^2 - 36x = 0

take out 9x

9x(x-4)

set equal to zero

9x = 0    x-4=0

0 and 4
