Question

Use the quadratic formula to find the zeros of the function y = 2x2 + 3x + 6. Round to the nearest tenth if necessary.

Answer 1

If you graph this equation it doesn't intercept the x axis.

Answer 2

so no real solution?

Answer 3

If an equation is of the form:
Ax^2 + Bx + C = 0,
then,
\[x = [-B \pm \sqrt{B^2 - 4AC}] \div (2A)\]
Just pull out what A, B, and C are, then plug 'em into the above equation and solve. Supersimple and easy. That's what's cool about the quadratic formula.
