Question

Factor: 9x^2 + 15x - 14

Answer 1

9x^2+15x-14
=(3x-2)(3x+7) is your final answer. Hope it help!

Answer 2

To solve this answer we use the quadratic formula
which is: x = -b +- square root b^2 - 4ac / 2a
a=9
b=15
c= -14
then simply plug in,

-15 +- square root 15^2 - 4(15)(-14)/2(9)
 ( Honestly you can use a website called desmos for quadratics but this is how you do it by hand)
 so , x= -2.333, x= 0.667
