Question

Solve for x. (X+10)(x+10)=0

Answer 1

X = -10

Explanation:

Adding negative ten and ten results in zero, and zero multiplied by anything is, of course, still zero.

(-10 + 10) * (-10 + 10) = 0

0 * 0 = 0

Answer 2

use foil method-first inside outside last

Explanation:

Answer 3

X=-10

Because (x+10)(x+10)=0

So it becomes (x+10)^2=0

And therefore x=-10
