Math Problem Statement

Solve the quadratic equation x^2 + 2(m-1)x + (m+5) = 0

Solution

The given equation is:

x2+2(m1)x+(m+5)=0x^2 + 2(m - 1)x + (m + 5) = 0

This is a quadratic equation in xx, where mm is a parameter. To solve this equation, we can apply the quadratic formula:

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

For the equation ax2+bx+c=0ax^2 + bx + c = 0, we identify the coefficients as:

  • a=1a = 1,
  • b=2(m1)b = 2(m - 1),
  • c=m+5c = m + 5.

Substituting into the quadratic formula:

x=2(m1)±[2(m1)]24(1)(m+5)2(1)x = \frac{-2(m - 1) \pm \sqrt{[2(m - 1)]^2 - 4(1)(m + 5)}}{2(1)}

Let me simplify this for you.The solutions to the quadratic equation x2+2(m1)x+(m+5)=0x^2 + 2(m - 1)x + (m + 5) = 0 are:

x1=m(m4)(m+1)+1x_1 = -m - \sqrt{(m - 4)(m + 1)} + 1 x2=m+(m4)(m+1)+1x_2 = -m + \sqrt{(m - 4)(m + 1)} + 1

These are the two roots of the equation in terms of the parameter mm.
