Question

Anyone Help please??!!!

Answer 1

Hello.

When we are factoring squared binomials, there’s a pretty simple technique to solving for these.

First, square root the first term (x^2). We get x. Now, let’s square root our second term (100), which we get 10.

Put our square-rooted terms into parenthesis; (x + 10)

Since we have a negative sign before 100, we need to add a second parenthesis with the same terms, but 10 now needs to be negative; (x - 10)

Put these two parenthesis next to eachother, and now we have our answer, as we cannot simplify it anymore;
(x - 10)(x + 10)

I hope this helps!

Answer 2

find 2 numbers when multiplied by each other = 100

sqrt(100) = 10

since the equation has a minus sign

the answer would be (x+10)(x-10)
