You are watching: How to factor x 2 36
To solve the equation, element the left hand side by grouping. First, left hand side demands to be rewritten together 2x^2+ax+bx-36. To find a and b, set up a system to it is in solved.
Since ab is negative, a and b have the the opposite signs. Because a+b is negative, the an adverse number has higher absolute worth than the positive. List all together integer pairs that provide product -72.

Rearrange the polynomial to placed it in conventional form. Place the terms in stimulate from highest to lowest power.
To settle the equation, aspect the left hand next by grouping. First, left hand side requirements to it is in rewritten together 2x^2+ax+bx-36. To discover a and b, set up a device to it is in solved.
Since abdominal is negative, a and also b have actually the the contrary signs. Because a+b is negative, the an adverse number has greater absolute value than the positive. List all together integer bag that offer product -72.
All equations that the type ax^2+bx+c=0 can be fixed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula gives two solutions, one when ± is addition and one as soon as it is subtraction.
This equation is in typical form: ax^2+bx+c=0. Substitute 2 because that a, -1 for b, and also -36 for c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Divide -frac12, the coefficient the the x term, by 2 to gain -frac14. Then add the square that -frac14 come both political parties of the equation. This step makes the left hand next of the equation a perfect square.
