Question

(x+m)(x+n) if m=5 and 7 n=7

Answer 1

x^2 + 12x + 35

Explanation:

Use the FOIL approach to find the product of (x+m)(x+n); it is x^2 + mx + nx + mn.

Next, substitute 5 for m and 7 for n in this x^2 + mx + nx + mn:

x^2 + 5x + 7x + 35, or

x^2 + 12x + 35

This end result cannot be simplified or evaluated further.
