Explanation Given: The expression is x 2 = 3 ( x − 3 ) . Formula used: Consider the quadratic equation a x 2 + b x + c = 0 . Write the expression for roots of the quadratic equation. x = − b ± b 2 − 4 a c 2 a Here, a , and b are the coefficient of x 2 and x respectively. Also, c represents the constant term. Calculation: The expression is x 2 = 3 ( x − 3 ) . Simplify the expression in standard form. x 2 = 3 ( x − 3 ) x 2 = 3 ⋅ x − 3 ⋅ 3 x 2 = 3 x − 9 Further, solve. x 2 − 3 x + 9 = 0 Now, refer the expression for roots of the quadratic equation. The expression in standard form is x 2 − 3 x + 9 = 0 . The value of a , b , and c are 1 , − 3 , and 9 , respectively. Find the roots for the equation x 2 = 3 ( x − 3 ) by using the quadratic formula
