The function k(x)=-x2-2x+15 can be re-written as k(x) = -x^2 - 2x + 15, which in turn becomes -(x^2 + 2x - 15) after the negative sign is factored out. com/How-do-you-factorize-x-2-2x-15 Thanks for the A2A Look at the coefficient of x2 and the constant. uk Tech Specs: Transducer type: Dynamic. Detailed step by step solution for X^2+2X-15=0. Find the value of using the formula. Simplify (x 2 – 4) / (x 2 + 4x + 4) Solution Factor both the numerator and denominator to get.
