How do you solve x plus 9 equals x squared? - Answers

By factorising:x + 9 = x2x2 - x - 9 = 0(x - 3.54)(x + 2.54) = 0x = 3.54, x = -2.54By the quadratic formula:x = -(-1) ± √[(-1)2 - 4(1)(-9)]/2(1)x = 1 ± √(1 - -36)/2x = 1 ± √37/2x = 0.5 ± 6.08/2x = 0.5 + 3.04 = 3.54, x = 0.5 - 3.04 = -2.54The same solutions are given both ways, which confirms the result.
