Explanation Formula used: For a quadratic equation in standard form, a x 2 + b x + c = 0 , a ≠ 0 , the quadratic formula is x = − b ± b 2 − 4 a c 2 a . Calculation: Obtain the solution of the equation 3 x 2 − 6 x − 5 = 0 . Compare the equation 3 x 2 − 6 x − 5 = 0 into standard quadratic equation a x 2 + b x + c = 0 , a ≠ 0 then a = 3 , b = − 6 and c = − 5 . Substitute the values of a , b , c in the quadratic formula x = − b ± b 2 − 4 a c 2 a , x = − ( − 6 ) ± ( − 6 ) 2 − 4 ( 3 ) ( − 5
