Remember, quadratic function is in the form 0 = ax^2 + bx + c After you have put the formula in that form, simply use the quadratic formula: \[x = \frac{ -b \pm \sqrt{b ^{2} - 4ac} }{ 2a }\]

To get your original equation in quadratic form, simply subtract x^2 from both sides, so you're left with 0 = 1x^2 - 7x + 4 (I rearranged it so it's easier to follow.) Now, plug in the numbers in the equation I gave you above, but not in a calculator.
