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.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
