X2 10x 21 0
x^{2}+10x+21=0 All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. Given equation: x 2-10 x + 21 = 0. x 2-10 x + 21 = 0 ⇒ x 2-7 x-3 x + 21 = 0 ⇒ x x-7-3 x-7 = 0 ⇒ x-7 x-3 = 0. Step 2: Determine the roots of the equation. Thus, the given equation can be written as, x-7 x-3 = 0. So, either, x-7 = 0 ⇒ x = 7. Or, x-3 = 0 ⇒ x = 3. Therefore, the solutions to the given quadratic equation are x = 7 and x = 3.
