Question

Find the sum of the roots of the equation x² –  8x + 2 = 0

Options

• 8

• –8

• 2

• –6

Answer 1

8

Explanation:

For general quadratic equation ax² + bx + c = 0.

Sum of the roots = `(−"b")/"a"`

For x² – 8x + 2 = 0

Sum of the roots = `(−(−8))/1` = 8

Sum of the roots of the equation is 8.
