Explanation: x2 +10x +24 = 0. We are going to create a perfect square trinomial on the left side of the equation, then solve for x. The general equation for a perfect square trinomial is a2 +2ab + b2 = (a + b)2. Subtract 24 from both sides. x2 +10x = −24. Divide the coefficient of the x term by 2, then square the result, and add it to both sides.

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.Dimitri is solving the equation #x^2 - 10x = 21#.
