how many solutions and what kind of solutions would be for the quadratic equation For X squared plus 20 X plus 25. Let's go ahead and find our A, B and C because we need those for the discriminate. So our a s four RBs 20 r c is 25. We need those because the discriminate says B squared minus for a C. So we're gonna have 20 square minus four times, four times 25. So that's going to give May 400 minus 400 which equals zero. When my discriminate equals zero, we're gonna have one riel rational roots.
