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
