Math Problem Statement

(x-2)^2 + 5(x-2) + 6=0

Solution

To solve the equation (x2)2+5(x2)+6=0(x-2)^2 + 5(x-2) + 6 = 0, we can start by making a substitution to simplify it.

Let y=x2y = x - 2. This gives us:

y2+5y+6=0y^2 + 5y + 6 = 0

Now, we need to solve this quadratic equation. The standard form of a quadratic equation is ay2+by+c=0ay^2 + by + c = 0. In this case, a=1a = 1, b=5b = 5, and c=6c = 6.

We can use the quadratic formula y=b±b24ac2ay = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}:

y=5±5241621y = \frac{-5 \pm \sqrt{5^2 - 4 \cdot 1 \cdot 6}}{2 \cdot 1}

y=5±25242y = \frac{-5 \pm \sqrt{25 - 24}}{2}

y=5±12y = \frac{-5 \pm \sqrt{1}}{2}

y=5±12y = \frac{-5 \pm 1}{2}

So, we have two solutions for yy:

y=5+12=42=2y = \frac{-5 + 1}{2} = \frac{-4}{2} = -2

y=512=62=3y = \frac{-5 - 1}{2} = \frac{-6}{2} = -3

Since y=x2y = x - 2, we can now substitute back to find the values of xx:

For y=2y = -2:

x2=2x - 2 = -2

x=0x = 0

For y=3y = -3:

x2=3x - 2 = -3

x=1x = -1

Therefore, the solutions to the original equation are x=0x = 0 and x=1x = -1.
