Answer:
f(-3) = 27
Step-by-step explanation:
f(-3) = (-3)^2 - 5(-3) +3
f(-3) = 27
The ordered pairs of the solutions for this system of equations will be 3,2
Quadratic equation
- In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0
- Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0.
How to solve this problem?
The steps are as follow:
- Given equation
f(x) = x^2 – 5x + 3
- Putting value of x as -3 we will get
f(x) = (x)^2 - 5(x) + 3
-3 = (x)^2 - 5(x) + 3
(x)^2 - 5(x) + 6 = 0
(x-3)(x-2) = 0
x = 3 or x = 2
So the ordered pairs of the solutions for this system of equations will be 3,2
