How do you solve the equation by completing the square: x^2 - 14x + 33 = 0 Completing the Square: In the elementary algebra, the completing the square method is applied to solve the quadratic equation. In this method, we use basic formula[(a±b)2=a2±2ab+b2]to tran...
To complete the square, move 'c' to the other side of the equation: ax^+bx=-c. Then, divide everything by 'a' so it looks like x^2+bx/a=-c/a. Then, add (b/2a)^2 to both sides. This forces the left-hand side to be a perfect square and therefore factorable. This leads...
In any quadratic, before you complete the square, you first divide through by the leading coefficient to make it 1. In your case of a2 - 2a - 8 = 0, the leading coefficient is already 1. Now you can complete the square. If the linear coefficient is 2r then you want to make the ...

Factoring the quadratic will change it from standard form into intercept form, which will tell us exactly where the parabola crosses the x-axis (where its x intercepts are), or in this problem, where the bird hits the ground. To factor a quadratic, it's really nice not having a ...

The biggest benefit of repurposing a bonus room is that it creates additional space for the family. “Adding additional square footage to the home by converting an unfinished bonus room into a finished space is typically less expensive than adding space by expanding the existing footprint,” Verna...
A factor pair is just two numbers that multiply and give you c. Out of all of the factor pairs from step 1, look for the pair (if it exists) that add up to b Note: if the pair does not exist, you must either complete the square or use the quadratic formula. Insert the pair...
