You know the formula of discriminant

a b
c d
that means ad-bc
So <span>we have an equation
(-12)x3-(2f)x(-w</span>²)= 2k x 3- (-14)x(-81)
0r -36 +2fw²= 6k- 1134
And 2fw²-6k+ 1098=0
But I did not know what is variable here?

If f(x) = x/2 - 3 and g(x) = 3x^2 + x - 6, find (f+g)(x)

drek231 [11]

$(f+g)(x) = f(x) +g(x)$

$(f+g)(x) = \left(\dfrac{x}{2}-3\right)+\left(3x^2+x-6\right)$

$(f+g)(x) =3x^2 +\dfrac{3x}{2}-9$
