Question

Determine the solutions of the quadratic equation, 2 x squared minus 8 x plus 6 equals 0 using the quadratic formula. x equals the fraction with numerator negative b plus or minus the square root of b squared minus 4 a. c and denominator 2 a.

Answer 1

1, 3

Explanation:

2x^2 - 8x + 6 = 0 -->

x^2 - 4x + 3 = 0

(x-1)(x-3) = 0

x = 1, 3

OR

2x^2 - 8x + 6 = 0 -->

x^2 - 4x + 3 = 0 -->

(-(-4) +-sqrt((-4*-4) -4(1 * 3)))/2 -->

(4 +-sqrt(4))/2 -->

(4 +/-2)/2 -->

6/2 or 2/2 -->

3, 1
