9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
The discriminant of a quadratic ax2 + bx + c is b2 - 4ac; thus: the discriminant of -9x2 + 6x + 14 is 62 - 4 x -9 x 14 = 540
9x2+6x-8 = 0 (3x+4)(3x-2) = 0 Therefore: x = -4/3 or x = 2/3
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
The discriminant is 0.

The discriminant is 0.
It is: 3x2+6x-11 = 0
From what i understand the equation is like this; (3 * 2 ) + 6x + 24 = 0 6 + 6x +24 = 0 6x = - 24 - 6 6x = - 30 x = - 5
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
7x + 2 = 6x + 2 if and only x = 0.
9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}
x+15+(-15)=6x+(15+(-15)=6x+(15-15)=6x+(0)=6x+0=6Add/subtract 0 from both sides,x=6
6x+5=3x+5 5=9x+5 x=0
