Question

6x^2-15x-9=0 plz help ​

Answer 1

Solution

6x²-15x-9=0

=>6x²-18x+3x-9=0

=>6x(x-3)+3(x-3)=0

=>(x-3)(6x+3)=0

either...x-3=0=>x=3

or.....6x+3=0=>x=-(1/2)

hope this helps you....

Answer 2

Answer:

$6x {}^{2} - 15x - 9 = 0 \\ 6x {}^{2} - 9x - 6x - 9 = 0 \\ 3x(2x - 3) - 3(2x - 3) = 0 \\ (2x - 3)(3x - 3) = 0 \\ x = \frac{3}{2} \\ x = 3$
