Question

Solve using quadratic formula >>>5x^2-7x-3=0 ????

Answer 1

Okay; so you are given a function which is in the form A(x^2)+Bx+C=0 right?

So in this case your
A=5
B=-7
C=-3

then using the quadratic formula, which I'm not sure if you are familiar with
you can use it to find 'x'

So x=\[(-B \pm \sqrt{B^2-(4*A*C)})/2A\]

Substitute in your values of A,B and C to find your two values of 'x'
