Question

solve this quadratic equation to use formula

Answer 1

Hi,

10ax - 6x + 15ax - 9 = 0 or 
10ax  + 15ax - 6x - 9 = 0
5ax(2x + 3) - 3(2x + 3) = 0
(5ax - 3)(2x + 3) = 0
(5ax - 3) = 0  or  (2x + 3)=0

So the answer will be  x = 3/5a  or  x = -3/2

Hope it helped

Answer 2

Answer:

x = 3/(5a)  or  x = -3/2

Step-by-step explanation:

Solve this quadratic equation by splitting the middle term,

10ax - 6x + 15ax - 9 = 0,

10ax  + 15ax - 6x - 9 = 0

Splitting the middle term

5ax (2x + 3) - 3(2x + 3) = 0

(5ax - 3)(2x + 3) = 0

(5ax - 3) = 0  or  (2x + 3)=0

The value of x = 3/(5a)  or  x = -3/2
