How to solve negative square roots
Web1 I try to solve the equation f ( x) = 7 x − 11 − 2 x 2 = 0 for x, but run into troubles. I've gone through it over and over again as well as similar problems, but can't find what I'm doing wrong. f ( x) = 7 x − 11 − 2 x 2 = 0 x 2 − 7 2 x + 11 2 = 0 ( x + 7 4) 2 = ( 7 4) 2 − 11 2 x + 7 4 = ± ( 7 4) 2 − 11 2 x = − 7 4 ± 49 16 − 88 16 Webis the formula for displacement out of which we can get a quadratic equation to solve for t (time) 0 = 5 t 2 + sin ( 28) 35 t + 52 Now when I plug that into the quadratic formula it gives me a negative under the square root and we are definitely not working with complex numbers. How do I solve for t? Thanks, John. physics quadratics Share Cite
