9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
(3x+4)(3x-4)=0 x=±4/3
3x6, 9x2, 18x1,
x = 4
9x2+11x-14 = (9x-7)(x+2) when factored with the help of the quadratic equation formula.
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
9x2-810 is not an equation. It has to be equal to something to be an equation. Therefore it cannot be solved.
(3x+4)(3x-4)=0 x=±4/3
9x2=18
If you mean y =9x^2 -4 , than the range is the possible y values. Range = 0<= y < infinity.
x = 4
3x6, 9x2, 18x1,
9x2+11x-14 = (9x-7)(x+2) when factored with the help of the quadratic equation formula.
18x1, 9x2, 6x3, 12x1.5, etc
The discriminant is 0.
(((9x2)+7)-5)=20 that is 9x2=18 18+7= 25 25-5=20
