How do you solve this equation to the nearest hundredth x squared -7x -12 equals 0?
Using the quadratic equation formula: x = 8.42 or x = -1.42
Y equals b plus x plus x2?
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
Solve the quadratic equation using factoring x2 3x 2 0?
x2+3x+2=0 (x+2)(x+1)=0 x=-2 or -1
How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
X2 - 3x - 18?
I assume your trying to solve for the x variable? Use the quadratic formula (Google it) to find the roots to a second order equation (equation that contains a variable to power of 2). Using that equation, you get x values of 6 and -3. The only other way to solve it is with trial and error, which can be quite tedious.
