You are watching: Factor x^2-36
To fix the equation, aspect the left hand next by grouping. First, left hand side needs to be rewritten together 2x^2+ax+bx-36. To uncover a and b, collection up a mechanism to be solved.
Since ab is negative, a and also b have actually the opposite signs. Due to the fact that a+b is negative, the an unfavorable number has better absolute worth than the positive. List all together integer pairs that provide product -72.

Rearrange the polynomial to placed it in standard form. Place the state in stimulate from greatest to lowest power.
To resolve the equation, variable the left hand next by grouping. First, left hand side requirements to be rewritten as 2x^2+ax+bx-36. To uncover a and b, set up a system to be solved.
Since abdominal is negative, a and also b have actually the opposite signs. Due to the fact that a+b is negative, the an unfavorable number has greater absolute worth than the positive. Perform all together integer pairs that give product -72.
All equations the the type ax^2+bx+c=0 have the right to be addressed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula provides two solutions, one when ± is addition and one as soon as it is subtraction.
This equation is in conventional form: ax^2+bx+c=0. Instead of 2 for a, -1 for b, and -36 because that c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Divide -frac12, the coefficient of the x term, through 2 to obtain -frac14. Then add the square the -frac14 come both political parties of the equation. This step makes the left hand side of the equation a perfect square.
