# When using the quadratic formula to solve a quadratic equation ax2 + bx + c = 0, the discriminant is b2 – 4ac.

When using the quadratic formula to solve a quadratic equation ax2 + bx + c = 0, the discriminant is b2 – 4ac. This discriminant can be positive, zero, or negative. (When the discriminant is negative, then we have the square root of a negative number. This is called an imaginary number, sqrt(-1) = i. [...]

# Solve using the quadratic formula?

Use the Quadratic Formula to solve. x^2 – 8x + 2 = 0 show in steps please, thanks! ok, so how did you guys get 4 +- sqrt(14) and I got 4 +- 2sqrt(14) The sqrt can be broken down to 2sqrt(14) what did I do wrong?

# simplifying 2(x+2)+4(x+1) = -3(x+1)(x+2) into standard form and using the quadratic formula for solutions?

How do you simplify 2(x+2)+4(x+1) = -3(x+1)(x+2) into standard form and then use the quadratic formula for solutions. I think I may have figured out how to get it into standard form and get -3x^2-15x-14 but I believe the book may have the quadratic formula use wrong and need some help to make sure or [...]
