12x11 is 132
If you mean: x2+8x-9 = 0 then the solutions are x = 1 and x = -9
The Answer to x2-10x250 is negative 2500, also -2500.
Id x2 = 169, then x = ±√169 = {-13, +13}
x2-10 = 0 x2 = 10 x = the square root of 10
If: x2 = 3 Then: x = square root of 3
12x11=132
The product is 132
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
x2 = 81 Square root both sides:- x = +/- 9
x2 + 49 = 0
x^2<25
