Question

factor 13x-20-2x^2

Answer 1

Factor a minus sign out of \(-2 x^2+13 x-20.\)
Factor -1 out of \(-2 x^2+13 x-20:\)
\(-(2 x^2-13 x+20)\)
Factor \(2 x^2-13 x+20\) by finding factors of \(2×20\) whose sum is -13.
Factor the quadratic \(2 x^2-13 x+20.\) The coefficient of \(x^2\) is 2 and the constant term is 20. The product of 2 and 20 is 40. The factors of 40 which sum to -13 are -5 and \(-8. So 2 x^2-13 x+20 = 2 x^2-8 x-5 x+20 = x (2 x-5)-4 (2 x-5):
-x (2 x-5)-4 (2 x-5)\)
Factor common terms from \(x (2 x-5)-4 (2 x-5).\)
Factor \(2 x-5\) from \(x (2 x-5)-4 (2 x-5):\)
