1800 = -3p^2+70p+988 0 = -3p^2+70p - 812 Using the discriminant means taking the section of the quadratic formula: âšâ€‹(b^2)â’4ac And by plugging in the values of our formula we get: âšâ€‹(70^2)â’4*-3*-812 Which yields: âšâ€‹4900 â’ 9744 Since this is a square root of a negative number, it says there is no real solution for the formula, which makes sense because the formula is a quadratic that is pointing downwards (a = -3p^2) and underneath the number line (c = -812). ​ ​​ ​​
