Question

Solve the quadratic equation. x2+x+5=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

Use the quadratic formula: x = [-1 ± sqrt(1 - 20)]/2 = [-1 ± sqrt(-19)]/2.

Solutions:
x = (-1 + i√19)/2
x = (-1 - i√19)/2
