Factorise the equation 2x^2=x-15

Answer»

Answer:

Step-by-step EXPLANATION:

2x^{2} = x - 15\\2x^{2} - x + 15 = 0\\

PLEASE check if this is the question correct and if correct then here are it's non real roots

a = 2, b = -1, c = 15\\D = b^{2} - 4ac\\D = (-1)^{2} - 4 (2)(15)\\D = 1 - 120\\D = -119\\\\D < 0 \\It- will- have -non -real -roots\\Using -quadratic -formula \\x = \frac{- b ± \sqrt{D}}{2a} \\\\x =\frac{ -(-1) ± \sqrt{-119} }{2 (2)}\\x = \frac{1± 119i }{4}

Just ignore the SYMBOL before ± it's  the fault of equation INSERTION
