Question

Consider the equation:
24 = x2 – 4x + 3
1) Rewrite the equation by completing the square.
Your equation should look like (x + c)2 = d or (2 — c)2 = d.
2) What are the solutions to the equation?
Choose 1 answer:
X = 2 5
x = -2 +5
x = 2 + 5
x = -2 + 5

    Answer:

            1)  (x – 2)² = 25

            2)   x = 2 ± 5

    Step-by-step explanation:

    24 = x^2 - 4x + 3\\\\ x^2 - 4x + 3-24=0\\\\\underbrace{x^2-2\cdot x\cdot2+2^2}-2^2-21=0\\\\{}\qquad(x-2)^2-25=0\\\\{}\qquad\bold{(x-2)^2=25}\\\\{}\qquad x-2=\pm\sqrt{25}\\\\{}\qquad \bold{x=2\pm5}
