Make y the subject of the formula x=a-2by^2

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Find the condition that the zeros of the polynomial f(x) = x^3+3px^2+3px+r may be in a. p.

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
