Question

Factor 8a squared - A - 30

Answer 1

Answer:

1 Split the second term in 8{a}^{2}-a-308a

2

−a−30 into two terms.

1 Multiply the coefficient of the first term by the constant term.

8× -30= -240

2 Ask: Which two numbers add up to -1 and multiply to −240?

15and -16

3 Split -a as the sum of 15a and −16a.

8{a}^{2}+15a-16a-30

8{a}^{2}+15a-16a-30

2 Factor out common terms in the first two terms, then in the last two terms.

a(8a+15)-2(8a+15)

3 Factor out the common term 8a+15

(8a+15)(a-2)
