Use the quadratic formal to solve the equation (show all work) (m-4)(3m-10)=3(m-2)+18
Find the value of the discriminant describe the number and types of roots find the exact solutions bybusing the quadratic formula
I'm solving a quadratic equation which is 2x^2-x-10=0 and I know that a=2 b=-1 and c=-10 ans with the problem put it into the formula which is -(-10 +- √ -1^2-4(2)(-10) and when I get my answer...

I'm trying to solve the quadratic formula with these numbers, but my answers always ended up not being whole numbers. Can you solve it for me and tell me what you get?
What's the answer
I dont understand how to solve quadratic functions. I'm supposed to solve f(x)-x^2+2x-3 by completing the square but whenever I try to search how to do these kind of problems, I never see...
the problem 7x^2+123x-4
I know how to graph these kinds of equations with parabolas but cannot figure out how to find the factored, vertex, and standard forms of these equations.
use the quadratiic formula
how do you solve?
