Question

A quadratic equation is missing the “c” value: x²+20x+c=0.

Determine ONE (1) integer value of “c” that would result in TWO SOLUTIONS

Answer 1

100

Explanation:

`{x}^(2) + 20x + c \\ \\ {x}^(2) + 2.x.10 + {10}^(2) \\ {x}^(2) + 20x + 100 \\ \implies \: {x}^(2) + 20x + c \\ \implies \: c = 100`
