Question

Solve the quadratic equation by using the square root property. 
D) no solution

Quizplus · Accepted Answer

Since the square root property states that if $ax^2+bx+c=0$ then $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$, we can plug in the coefficients from the given quadratic equation, $2x^2+5x-3=0$, to get $x=\frac{-5\pm\sqrt{5^2-4(2)(-3)}}{2(2)}$. Simplifying, we get $x=\frac{-5\pm\sqrt{61}}{4}$. Therefore, the answer is B.
