Question

How many solutions are there form 5x^2+7x-4=0?

my answer is 3

Answer 1

nope. There are exactly as many roots as the degree of the polynomial. In this case, 2, since the highest power is x^2.

There are three terms, but only two solutions. Recall your quadratic formula. It only produces two values.
