Question

What expression is equivalent to n^2+26n+88 for all values of n.

A. (n+8)(n+11)
B. (n+4)(n+22)
C. (n+4)(n+24)
D. (n+8)(n+18)

Answer 1

When using the X method to solve, you can plug in the values given to you in the answers. 8 and 11 multiplied does equal 88 but when added they don't equal to 26 so A is wrong. 4 and 22 do equal 26 but when multiplied, they don't equal to 88 so B is also wrong. 22 and 4 added together equals 26 and multiplied it equals to 88. So C is your answer.
