To find a and b, set up a system to be solved. a=-3 b=-1 . Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system solution.

Okay, so for two simultaneous equations which both equal the same variable (in this example the variable they're equal to is y), the trick is to make both equations equal each other:so we can say that 4x + 1 = 5x^2 + 4x - 19This is very useful, because now that our equation only has x's in it, we can put everything onto one side, and solve itNote: it's easier to solve positive quadratic From the point (15, 12), three normals are drawn to the parabola y^2 = 4x. The centroid of the triangle formed by the feet of the normals is asked Nov 4, 2019 in Mathematics by SudhirMandal ( 53.5k points) Hi, quick help with a question: Express 4x^2-4x-3 in the form (ax-b)^2-c, where a, b and c are positive constants to be found.
