factor the expression through grouping. First, the expression needs to be rewritten together 2x^2+ax+bx-12. To find a and also b, set up a system to be solved.

You are watching: Factor 2x^2+5x-12


Since ab is negative, a and also b have the opposite signs. Due to the fact that a+b is positive, the hopeful number has better absolute value than the negative. Perform all together integer pairs that provide product -24.

Factor the expression through grouping. First, the expression requirements to be rewritten together 2x^2+ax+bx-12. To discover a and b, collection up a system to be solved.
Since ab is negative, a and also b have the the opposite signs. Because a+b is positive, the positive number has better absolute worth than the negative. List all such integer pairs that give product -24.
Quadratic polynomial have the right to be factored using the revolution ax^2+bx+c=aleft(x-x_1 ight)left(x-x_2 ight), whereby x_1 and also x_2 are the services of the quadratic equation ax^2+bx+c=0.
All equations that the type ax^2+bx+c=0 can be resolved using the quadratic formula: frac-b±sqrtb^2-4ac2a. The quadratic formula provides two solutions, one when ± is enhancement and one once it is subtraction.
