Q. x−2x2+3x−a=x+5Given the equation for all x=2, what is the value of a ?
Given Equation: We are given the equation:(x2+3x−a)/(x−2)=x+5To find the value of a, we need to solve this equation for a. Since the equation is valid for all x not equal to 2, we can multiply both sides by (x−2) to eliminate the denominator.(x2+3x−a)=(x+5)(x−2)
Eliminate Denominator: Now we will expand the right side of the equation:(x+5)(x−2)=x2−2x+5x−10Simplify the terms:x2+3x−10
Expand Right Side: Next, we will set the left side of the equation equal to the simplified right side: x2+3x−a=x2+3x−10
Set Equal: Since the x2 and 3x terms are on both sides of the equation, they cancel each other out. We are left with:−a=−10
Cancel Terms: To find the value of a, we divide both sides by −1:a=10
