What is the solution set of (x - 2)(x - 3) = 2?.

Will give brainliest series to sigma notation write the following series in sigma notation. 6+10+14+18+22+26+30 example image shown below.

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

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
