Question 978600
Hi there
1.2x^2 - 8x = 2x(x - 4)
2.-3s^2 + 9s = -3s(s - 3)
3.4x + 20x^2 = 4x(1 + 5x)
4.5t- 10t^2 = 5t(1 - 2t)
5.s^2 + 8s + 12 = (s + 2)(s + 6)
6. x^2 - 10x + 21 = (x - 3)(x - 7)
7.x^2 + 5x - 6  = (x - 1)(x + 6)
8. 4r^2 + 20r + 25 = (2r + 5)(2r + 5)
9. 9t^2 - 4 = (3t - 2)(3t + 2)
10. 2x^2 + 3x - 14 = (2x + 7)(x - 2)
Hope this helps:-)
