x2 4 11 Simplify 1 2x 10 points 2x1 2x 1 Solution11 We have

x+2 4 11. Simplify 1 2x+ [10 points] 2x-1 2x +1

11) We have given (x+2)/(2x-1) -4/(2x+1)

[(x+2)/(2x-1)]-[4/(2x+1)]=[(x+2)*(2x+1)-4*(2x-1)]/[(2x-1)*(2x+1)]

=[2x^2+4x+x+2-8x+4]/[(2x-1)*(2x+1)]

=[2x^2-3x+6]/[(2x-1)*(2x+1)]

=[2x^2-3x+6]/[4x^2-1] since we use formula (a+b)*(a-b)=a^2-b^2 as a=2x and b=1

(x+2)/(2x-1) -4/(2x+1) =[2x^2-3x+6]/[4x^2-1]
