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+5We need to find the value of a. To do this, we will multiply both sides of the equation 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 compare the coefficients from the left side of the equation to the right side:x2+3x−a=x2+3x−10Since the x2 and 3x terms are identical on both sides, we can equate the constants to find the value of a:−a=−10
Compare Coefficients: Finally, we solve for a:a=10
