Question and answer
Solve the quadratic equation by factoring. 5x2 - 8 = 39x
5x^2 - 8 = 39x; 5x^2 - 39x - 8 = 0; (5x + 1)(x - 8) = 0; 5x + 1 = 0; 5x = -1; x = -1/5; x - 8 = 0; x = 8 x = -1/5 or x = 8

5x^2 - 8 = 39x;
5x^2 - 39x - 8 = 0;
(5x + 1)(x - 8) = 0;
5x + 1 = 0; 5x = -1; x = -1/5;
x - 8 = 0; x = 8

x = -1/5 or x = 8

apply the quadratic formula to find the roots of the given function, and then graph the function:f(x) = x2 + 4
Weegy: f(x)=x^2-4 a=1,b=0,c=-4 x1= (0+sqrt(0+16))/2 x1=2 x2= (0-sqrt(0+16))/2 x2= -2 (More)

complete the square, and find the roots of the quadratic equation.x2 - 2/3x = 0 x = 1/2 (3-sqrt(37)) x = 1/2 (3+sqrt(37))
Weegy: x^2-(2/3)*x=0 x(x-(2/3)) = 0 so x=0 or x-(2/3)=0 - > x=0 or x=2/3 (More)

12x^2 - 10x - 42 = 0
2(2x + 3)(3x - 7) = 0;
2(2x + 3) = 0; 4x + 6 = 0; 4x = -6; x = -6/4; x = -3/2
3x - 7 = 0; 3x = 7; x = 7/3
Solution: x = -3/2 or 7/3

What do we do if the middle term of the quadratic equation (bx) is missing? Who wants to give the following a try? 2x2 + 1 = 0
Weegy: The syntax of quadratic equation that we are familiar with is ax^2+bx+c=0. This actually is an adfected quadratic equation. The real form is ax^2+b=0, which is a pure quadratic equation. 2x^2+1=0 or, 2x^2=-1. or, x^2=-1/2 or, x=sqrt(-1/2). (More)
