Question

What are the factors of the equation when it’s in factored form? 2a^2 + 8a - 15 = 3a - 3

Answer 1

(2a+3 ) (a-4 )=0

Explanation:

2a^2 + 8a - 15 = 3a - 3

Subtract 3a from each side

2a^2 + 8a-3a - 15 = 3a-3a - 3

2a^2 + 5a - 15 = - 3

Add 3 to each side

2a^2 + 5a - 15+3 = 3 - 3

2a^2 -5a -12=0

(2a+3 ) (a-4 )=0 These are the factors
