Question

Supply the number so that the quadratic equation below has 6 and 8 as it’s solutions.
x² - 14x +______ = 0

Answer 1

To find the number to complete the quadratic equation, we can use the fact that the sum of the solutions of a quadratic equation in the form of ax² + bx + c = 0 is equal to -b/a.

In this case, the sum of the solutions is 6 + 8 = 14.

So, the missing number that completes the quadratic equation is -14. The quadratic equation becomes:

x² - 14x + (-14) = 0
