Math Problem Statement

:x^2-6x-10=-3

Solution

Let's solve the quadratic equation:

x26x10=3x^2 - 6x - 10 = -3

Step 1: Move all terms to one side of the equation

Add 33 to both sides of the equation to get:

x26x10+3=0x^2 - 6x - 10 + 3 = 0

Simplifying, we have:

x26x7=0x^2 - 6x - 7 = 0

Step 2: Solve using the quadratic formula

The quadratic formula is given by:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

For the equation x26x7=0x^2 - 6x - 7 = 0, the coefficients are:

  • a=1a = 1
  • b=6b = -6
  • c=7c = -7

Substituting these values into the quadratic formula:

x=(6)±(6)24(1)(7)2(1)x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-7)}}{2(1)}

Simplify step by step:

x=6±36+282x = \frac{6 \pm \sqrt{36 + 28}}{2}

x=6±642x = \frac{6 \pm \sqrt{64}}{2}

x=6±82x = \frac{6 \pm 8}{2}

Step 3: Find the two possible values for xx

  1. x=6+82=142=7x = \frac{6 + 8}{2} = \frac{14}{2} = 7
  2. x=682=22=1x = \frac{6 - 8}{2} = \frac{-2}{2} = -1

Final Answer:

The solutions are:

x=7orx=1x = 7 \quad \text{or} \quad x = -1
