Find all real or imaginary solutins to each equation.

3y(2)+4v-1=0

You have two variables, y and v, in that equation, and cannot solve for both. Perhaps you typed it wrong. Please use a ^ rather than () to denote an exponent. Otherwise we won't know what your equations mean.

Learn the general solution of the quadratic equation
ax^2 + bx + c = 0

x = [-b +/- sqrt (b^2 - 4ac)]/2a
That is probably what you need to solve the problem you meant to type.
