The quadratic function f(x) = x² - 2x - 48 when solved is x = 8 or x = -6
What is the quadratic function when solved
From the question, we have the following parameters that can be used in our computation:
f(x) = x² - 2x - 48
When expanded, we have
f(x) = x² + 6x - 8x - 48
When factored, we have
f(x) = x(x + 6) - 8(x + 6)
So, we have
f(x) = (x - 8)(x + 6)
Set to 0
This gives
x - 8 = 0 or x + 6 = 0
Evaluate
x = 8 or x = -6
Hence, the quadratic function when solved is x = 8 or x = -6
