Full solution

Q. x2+3xax2=x+5 \frac{x^{2}+3 x-a}{x-2}=x+5 \newlineGiven the equation for all x2 x \neq 2 , what is the value of a a ?
  1. Given Equation: We are given the equation:\newline(x2+3xa)/(x2)=x+5(x^{2}+3x-a)/(x-2)=x+5\newlineTo find the value of aa, we need to solve this equation for aa. Since the equation is valid for all xx not equal to 22, we can multiply both sides by (x2)(x-2) to eliminate the denominator.\newline(x2+3xa)=(x+5)(x2)(x^{2}+3x-a) = (x+5)(x-2)
  2. Eliminate Denominator: Now we will expand the right side of the equation:\newline(x+5)(x2)=x22x+5x10(x+5)(x-2) = x^2 - 2x + 5x - 10\newlineSimplify the terms:\newlinex2+3x10x^2 + 3x - 10
  3. Expand Right Side: Next, we will set the left side of the equation equal to the simplified right side: x2+3xa=x2+3x10x^2 + 3x - a = x^2 + 3x - 10
  4. Set Equal: Since the x2x^2 and 3x3x terms are on both sides of the equation, they cancel each other out. We are left with:\newlinea=10-a = -10
  5. Cancel Terms: To find the value of aa, we divide both sides by 1-1:a=10a = 10
