Question

Factor as the product of two binomials. 81+18x+x^2

Answer 1

(x+9)(x+9)

Explanation:

To factor this expression, we first need to put into standard form, that is,
`ax^2 + bx + c`.

So it becomes
`x^2 + 18x + 81`

Now we need to find two numbers that:

A. When multiplied get us c (81)

B. When added get us b (18)

9 and 9 match those requirements, so out product of two binomials for this becomes (x+9)(x+9).

Hope this helped!
