Determine the number of solutions for each of the quadratics below. Note: You do not need to solve the quadratics. Homework Help ✎
(x − 5)2 = −6
312x2 + 514x + 181 = 0
(x + 3)2 − 10 = 0
4x2 + 49 = 28x
Can any real number be squared to get a negative number? Is there any real value for x that will make the equation true?
Try using the Quadratic Formula.
Add 10 to both sides.
Change the quadratic into perfect square form.
