Use the discriminant to describe the roots of each equation. then select the best description. 2 = x^2 + 5x a. double root b. real and rational roots c. real and irrational roots d. non-real roots

If the discriminate is equal to 0, then there is one real root multiplicity 2; if the discriminate is >0, then there are 2 real and rational roots; if the discriminate is <0, there are no-real roots because you can't take the square root of a negative number and get real roots. Our discriminate is found by subbing into the quadratic formula and taking into consideration ONLY what is under the radical. Ours is . That is a positive 33, so the discriminate is >0 but not a perfect square, so our answer is that there are 2 real and rational zeros or solutions or roots. They all mean the same thing.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
