Question

solve the factorisation 9x²+15x-14=0
plzz answer it

Answer 1

$9 {x}^{2} + 15x - 14 = 0 \\ 9x {}^{2} + 21x - 6x - 14 = 0 \\ 3x(3x + 7) - 2(3x + 7) = 0 \\ (3x - 2)(3x - 7) = 0$

To get roots, Put,
3x-2=0
and
3x-7=0

Therefore, x = 2/3
or x = 7/3

Answer 2

It will give..


9x²+ 21x - 6x-14
3x(3x+7) -2 (3x+7)

(3x-2), (3x+7)...
