You are watching: Factor x^2-36

To resolve the equation, factor 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, set up a device to be solved.
Since abdominal muscle is negative, a and also b have the the contrary signs. Due to the fact that a+b is negative, the negative number has greater absolute value than the positive. List all together integer bag that offer product -72. 2x2-36=x Two options were uncovered : x = -4 x = 9/2 = 4.500 Rearrange: Rearrange the equation by subtracting what is come the ideal of the equal authorize from both sides of the equation : ...

To resolve 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 b, collection up a system to it is in solved.
Since ab is negative, a and b have the the contrary signs. Due to the fact that a+b is negative, the an adverse number has better absolute worth than the positive. List all together integer bag that offer product -72.
All equations of the kind ax^2+bx+c=0 deserve to be addressed using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula offers two solutions, one when ± is addition and one when it is subtraction.
This equation is in typical form: ax^2+bx+c=0. Instead of 2 because that a, -1 because that b, and -36 for c in the quadratic formula, frac-b±sqrtb^2-4ac2a.
Divide -frac12, the coefficient the the x term, by 2 to obtain -frac14. Then add the square the -frac14 come both political parties of the equation. This step makes the left hand next of the equation a perfect square.
