WebComplete each statement in the steps to solve x2 – 6x – 7 = 0 using the process of completing the square. Isolate the constant by both sides of the equation. Add to both sides of x2 – 6x = 7 to form a perfect square trinomial while keeping the equation balanced. Write the trinomial x2 – 6x + 9 as squared. WebJul 10, 2024 · Explanation: The given equation: x2 +6x − 7 = 0. x2 +2 ⋅ 3 ⋅ x − 7 = 0. x2 +2 ⋅ 3 ⋅ x + 32 − 33 −7 = 0. (x +3)2 − 16 = 0. (x +3)2 = 16.
WebThe 25/4 and 7 is the result of completing the square method. To factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which becomes 5^2/2^2. WebSolution: Given equation x 2 +6x = 7. Using the method of completing the square, let us find the solution set that satisfies the equation. Divide the coefficient of the x term by 2 then square the result. This number will be added to both sides of the equation. Step 1: Rearrange the equation in the form of ax 2 + bx = c, if necessary.
