Convert to slope int. form: 4x+2y=8​

Convert the cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation. choices: r4 = -4r2 r2 = 4cos2θ r2 = 4sin2θ

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
