Question

Solve the quadratic equation. 4x2+7x+8=0 Write one exact, simplified solution in each box. You can add or remove boxes. If a solution is not a real number, write it in the form a+bi or a–bi, where a and b are real numbers.

Answer 1

The solutions are
x = (-7 + i√79)/8 and x = (-7 - i√79)/8

(Or x = -7/8 + (√79/8)i and x = -7/8 - (√79/8)i.)
