Question

If x₁,x₂ are the roots of the equation x² + 5x - 3 = 0, determine the value of x₁ + x_2.

Answer 1

,If x₁,x₂ are the roots of the equation x² + 5x - 3 = 0, determine the value of x₁ + x_2.

The two values of the quadratic equation are given as

X1 = ⌈-5+√(25 +4*3)⌉/2 = ⌈-5+√37⌉/2

and

X2 =⌈-5 - √(25 +4*3)⌉/2 = ⌈-5-√37⌉/2

Gives X1 +X2 = -10/2 = -5
