Answer:
3c) x = 1/4, x = 6
3d) t = 0, t = 4
Step-by-step explanation:
3c).....................................
- 6x² - 15x + 2 = 2x² + 10x - 4
- 4x² -25x + 6 = 0
- 4x² - 24x - (x - 6) = 0
- 4x(x -6) - (x - 6) = 0
- (4x - 1)(x - 6) =0
- 4x - 1 = 0 ⇒ 4x = 1 ⇒ x = 1/4
- x - 6 = 0 ⇒ x = 6
==============================
3d).....................................
- - 16t² + 76t + 5 = 12t + 5
- -16t² + 64t = 0
- t² - 4t = 0
- t(t - 4) = 0
- t = 0
- t - 4 = 0 ⇒ t = 4
