What are the solutions for the quadratic equation x2 minus 8x equals 9?
To solve a quadratic equation (which means to find the zeros of that equation) you have two options 1. type the equation into a graphing calculator and graph the resulting equation and find where the x intercepts are (where y=0) 2. solve the quadratic equation by factoring First, set the equation equal to zero. x2-8x-9=0 Then find the resulting x values by "smiling" multiply the first term and the last term (x2) (9) find two numbers that add to -8 and multiply to -9 these two numbers are -9 and 1 x2- 9x 1x-9 x(x-9) 1(x-9) the resulting factors are 0= (x+1)(x-9) to find the roots, set these factors = 0 x+1=0 x=-1 x-9=0 x=9 Therefore, the solutions for the quadratic equation are x=-1 and x=9

Solve x2 - 8x plus 32?
x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.
What are the solutions for the quadratic equation x2 plus 6x equals 16?
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.

What is the quadratic of this equation x2 plus 11x plus 11 equals 7x plus 9?
x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.
How do you factor x2-4x-80 equals 0?
Use the quadratic equation formula to find the solutions to this equation.
What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
