Question

find the roots of the quadratic equation 2 X square + X - 6 equal to zero by quadratic formula​

Answer 1

$2x^{2}+x-6\\ 2x^{2} +4x-3x-6\\2x(x+2)-3(x+2)\\x=-2 and 3/2$

OR

$D=B^{2} -4AC\\=1+48\\=49\\X=-1+7/4\\=3/2\\X=-1-7/4\\=-2$

Answer 2

Answer:

-2 and 3/2

Step-by-step explanation:

2x² + x - 6 = 0

also, 2x² + 4x - 3x - 6 = 0

also, 2x(x + 2) -3(x + 2) = 0

also, (x + 2)(2x - 3) = 0

Hence,

Either x = -2 or x = 3/2
