What is the discriminant of 8x2-2x plus 8 equals 0?
(-2)2-4*8*8 = -252 The discriminant is less than zero so there's no solution to the quadratic equation.
What is the answer to -4x2 minus 32x plus x plus 8 equals 8x2 minus 56x?
-4x2 - 32x + x + 8 = 8x2 - 56x : simplify and group the various terms-32x + 56x + x + 8 = 8x2 + 4x225x + 8 = 12x2 : Now present this as a standard quadratic equation.12x2 - 25x - 8 = 0 : Solving for the roots of a quadratic equation gives :-x = [25 ± √(252 + 4x12x8)] ÷ 2x12 = [25 ± √1009] ÷ 24 = [25 ± 31.765] ÷ 24x = 56.765/24 = 2.365 and x = -6.765/24 = -0.282x = 2.365 and -0.282

What are the factors of this quadratic trinomial 8x2 6x-9?
(4x - 3)(2x + 3)
How do you solve 8x2 plus 5x plus 6 equals 0?
Using the formula for the solution of a quadratic equation ax2+bx+c=0: x = (-b +- sqrt(b2-4ac)) / 2a (There are two roots, one is found by addition of the square root, the other by subtraction of it). Which for the given equation 8x2+5x+6=0 means a=8, b=5, c=6, giving: x = (-5 +- sqrt(52-4x8x6)) / (2x8) x = (-5 +- sqrt(25-192)) / 16 x = (-5 +- sqrt(-167)) / 16 which has no solution Unless you know about complex numbers and the use of i = sqrt(-1), in which case, the solutions are: x = -5/16 + 12.9i and x = -5/16 - 12.9i
Factor 8x2 plus 15 plus 26x?
