WebTo solve the equation, factor x^{2}-2x-8 using formula x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right). To find a and b, set up a system to be solved. ... the coefficient of the x term, by 2 to get -1. Then add the square of -1 to both sides of the equation. This step makes the left hand side of the equation a perfect … WebSolution. Verified by Toppr. x 2−2x−8. We can Split the Middle Term of this expression to factorize it.
What Is The Factor Of 2x - QnA
WebSal solves x²-2x-8=0 by rewriting the equation as (x-1)²-9=0 (which is done by completing the square!). ... You could also Not have B if you factor it out like this. A(B(x-C))^2 + D AB^2(x-C)^2 + D ... So if I were to expand out x plus a squared, that is x squared plus two a x, I'll make that plus sign you can see, plus two a x, plus a ... 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. greenway for american
