You are watching: How to factor x 2 36
To resolve the equation, factor the left hand side by grouping. First, left hand side needs to it is in rewritten as 2x^2+ax+bx-36. To uncover a and also b, set up a device to it is in solved.
Since ab is negative, a and also b have actually the the opposite signs. Due to the fact that a+b is negative, the negative number has better absolute value than the positive. List all together integer bag that offer product -72.

Rearrange the polynomial to put it in conventional form. Place the terms in bespeak from greatest to shortest power.
To settle the equation, aspect the left hand next by grouping. First, left hand side needs to it is in rewritten together 2x^2+ax+bx-36. To discover a and also b, collection up a system to it is in solved.
Since ab is negative, a and also b have the the opposite signs. Since a+b is negative, the an unfavorable number has greater absolute worth than the positive. List all such integer bag that give product -72.
All equations that the type ax^2+bx+c=0 deserve to be solved using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula offers two solutions, one once ± is enhancement and one once it is subtraction.
This equation is in traditional form: ax^2+bx+c=0. Instead of 2 because that a, -1 for b, and -36 because that c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Divide -frac12, the coefficient the the x term, through 2 to get -frac14. Then include the square the -frac14 to both sides of the equation. This step provides the left hand next of the equation a perfect square.

Factor x^2-frac12x+frac116. In general, when x^2+bx+c is a perfect square, it can always be factored together left(x+fracb2 ight)^2.
