State the quadratic formula.
need to state a quadratic formula and sove problems usein the quadratic formula
-b ± √ (b^2 - 4ac)
x = ----------------------
2a
You get a, b and c from the equation ax^2 + bx + c = 0
Use whatever values occupy those places in your specific equation.
E.G., if your equation were 7x^2 - 3.5x + 12 = 0, the
values would be a = 7, b = -3.5, c = 12
Plug those into the quadratic formula and solve it.
