Mai is using the quadratic formula to solve two different quadratic equations.For the first equation, she writes x=\frac{=-4\pm \sqrt{4^{2}-4(4)(2)}}{2(4)}For the second equation, she writes x=\frac{=3\pm \sqrt{(-3)^{2}-4(3)(5)}}{2(3)}How many real solutions will each equation have? Explain how you know.
