Question

solve quadratic equation using formula.x^2+x+5=0​

Answer 1

Step-by-step explanation:

x² + x + 5 = 0

a = 1, b = 1 and c = 5

x = [- b ± √(b² - 4ac)] / 2a

x = [- 1 ± √(1² - 4 × 1 × 5)] / 2 × 1

x = [-1 ± √-19] / 2

x = [- 1 + √- 19] /2 and [ - 1 - √-19] / 2

as D < 0, the given equation has no real solution
