Answer:
A: -5 ± √ 17 / 2
Step-by-step explanation:
Consider the following equations:
ax^2 + bx + c - This is an equation you use in understanding quadratic functions.
x= (−b± √b^2−4ac) / 2a - This is the quadratic formula used to solve quadratic functions
So: ax^2 + bx + c = x^2 + 5x + 2
SOLVE:
-(5) ± √ 5^2−4(1)(2)) / 2(1)
= -5 ± √ 25− 8 / 2
= -5 ± √ 25− 8 / 2
= -5 ± √ 17 / 2
