What must be true of an equation before you can use the quadratic formula to find the solutions?
the formula you are going to use to answer the 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.
Is y plus 6x equals -14 quadratic?
-8
What values best approximate the solutions of -4x2 plus 7x plus 5 equals 0?
Using the quadratic equation formula:- x = -0.5447270865 or x = 2.294727086
What are 3 other names for solutions of a quadratic equation?
