Use the quadratic formula to determine the exact solutions to the equation. x2? 4x? 8=0

x = 0

Step-by-step explanation:

Solve for x over the real numbers:

4 x^2 x^8 = 0

x^2 4 x^8 = 4 x^10:

4 x^10 = 0

Divide both sides by 4:

x^10 = 0

Take the 10^th root of both sides:

 x = 0

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
