Question

Factor completely. 8y^2 - 26y + 15 (4y - 3)(2y - 5) (2y - 3)(4y - 5) 2(2y - 3)(2y - 5)

Answer 1

Use the ac method:-

ac = 8*15 = 120

we need 2 factors of 120 which when added will equal -26

they are -20 and - 6 so we have

8x^2 - 20x - 6x + 15

= 4x(2x - 5) - 3(2x - 5)

= (4x - 3)(2x - 5) answer

Answer 2

8y^2 - 26y + 15

= (4y - 3)(2y - 5)

Hope it helps.
