Factorize each of the following algebraic expressions:a2 + 3a - 88

1.	Factorize each of the following algebraic expressions:a2 + 3a - 88
Answer» In order to factorize the given expression, we find to find two numbers p and q such that: p + q = 3, pq = -88 Therefore, split 3a as 11a – 8a Therefore, a² + 3a – 88 = a² + 11a – 8a – 88 = a (a + 11) – 8 (a + 11) = (x – 8) (a + 11)

Answer»

In order to factorize the given expression, we find to find two numbers p and q such that:

p + q = 3, pq = -88
Therefore, split 3a as 11a – 8a
Therefore,
a² + 3a – 88 = a² + 11a – 8a – 88

= a (a + 11) – 8 (a + 11)

= (x – 8) (a + 11)
