Question

Solve by using formula : x square --2x -- 2 =0.. ( formula : x = -- b +or -- root of b square -- 4ac divided by 2a

Answer 1

Answer:

THE QUADRATIC FORMULA The roots of the quadratic equation ax* + b x + c = 0, ... the constant to the right side, giving 2 . b C - - X* + – X = –– Divide by a Cl Cl 2 . ... Add || -- Cl 2a Cl 2a 2a b \* –4ac + b” x + , ) = − Perfect square 2a 4a Vb ... + 9 = 0 (c) x* + 2 x + 2 = 0 SOLUTION (a) In this quadratic equation a = 3, b = -5,
