Question

Partially factored form:

f(x) = (x − 3)(x + 3)(x2− 4x + 5)

Use the quadratic formula to identify the zeroes of x2 − 4x + 5.

Answer 1

-2i+1 and 2-i

Explanation:

Got it right on edge

Answer 2

• 2 +i
• 2 -i

Explanation:

For ax²+bx+c = 0, the solutions are ...

`x=(-b\pm√(b^2-4ac))/(2a)`

For the given quadratic term, a=1, b=-4, c=5, so the solutions are ...

`x=(-(-4)\pm√((-4)^2-4(1)(5)))/(2(1))=(4\pm√(-4))/(2)\\\\\boxed{x=2\pm i}`
