Factring and Polynomial

Question

Factor w2 + 8w + 16, if possible. If the polynomial is prime, say so


Factor 3y2 + 10y + 7, using the AC method. If the polynomial is prime, say so.

Answer 1

Hi, Belvia!

 

Okay, so let's factor w² + 8w +16

(w + 4)(w + 4)  = (w + 4)²

 

Now, factor 3y² + 10y + 7

Using AC method

A = 3, B = 10, C = 7

 

AC = 21

7 + 3 = 10  So,

(3y  + 7)(y + 1) are our factors
