Explanation Given: The provided equation is x ( 2 x + 3 ) = − 4 . Calculation: Now, expand the equation as below x ( 2 x + 3 ) = − 4 2 x 2 + 3 x = − 4 2 x 2 + 3 x + 4 = 0 Compare above with the standard quadratic equation a x 2 + b x + c = 0 , and use quadratic formula to find the value of x . Here, a = 2 , b = 3 , c = 4. Therefore, x = − b ± b 2 − 4 a c 2 a = − 3 ± 3 2 − 4 ( 2 ) ( 4
