Each solution to x^2 + 5x + 8 = 0 can be written in the form x = a+bi, where a and b are real numbers. What is a + b^2?
The quadratic x^2-3x+1 can be written in the form ,(x+b)^2+c where b and c are constants. What is b+c?
x^2 + 5 x + 8 = 0 has roots (solutions) - 5/2 +- sqrt (7)/2 i (obtained by Quadratic Formula)
so a + b^2 = -5/2 + (7/4) = - 10/4 + 7/4 = - 3/4
