Solve for x:x2 + 5x-(a2 + a-6) = 0

Answer»

x^2 + 5x - (a^2 + a - 6) = 0

x^2 + 5x - (a^2 + 3a - 2a - 6) = 0

x^2 + 5x - [a(a + 3) - 2(a + 3)] = 0

x^2 + 5x + (a + 3)(a - 2) = 0

x^2 + (a+3)x - (a-2)x + (a+3)(a-2) = 0

x(x + a + 3) - (a - 2)(x + a + 3) = 0

(x - a + 2)(x + a + 3) = 0

x = (a - 2), - (a + 3)

Sorry I can't di these
