Explanation Given: The given equation is, 12 x 2 − 5 x = 2... ( 1 ) Approach: The procedure to solve equation is as follow, Make the factors of the terms in the equation, if possible. If not, convert the given equation into standard form. Use the quadratic formula to solve the equation. The standard form for quadratic equation is, a x 2 + b x + c = 0... ( 2 ) The quadratic formula is, x = − b ± b 2 − 4 a c 2 a ... ( 3 ) Calculation: Add ( − 2 ) to both side in equation ( 1 ) . 12 x 2 − 5 x + ( − 2 ) = 2 + ( − 2 ) 12 x 2 − 5 x − 2 = 0 Compare the above equation with equation ( 2 ) . a = 12 b = − 5 And, c = − 2 Substitute 12 for a , ( − 5 ) for b and ( − 2 ) for c in equation ( 3 )
