3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
The discriminant b2-4ac is -23
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
Solve this problem -x squared -40x- 80 =0
If x squared -10 = 0 then x = the square root of 10

x = 25 / 3squared + 5
You have to put your heart into it!
Yes and x = 2+square root of 6 or x = 2-square root of 6
I suggest you use the quadratic formula, with a = 3, b = -2, c = 7.
So u have the function x2-4=0 Now because 4 is a squared number, its square root is 2 (x+2)(x-2)=0
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
x = -2/3,7/6
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
