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)
