Q. Given that (2x−1)28x2−6x+3=A+2x−1B+(2x−1)2C, then A= _____, B= _____, C= _____
Set up equation: Set up the equation for partial fraction decomposition.We are given the equation:(8x2−6x+3)/((2x−1)2)=A+(B/(2x−1))+(C/((2x−1)2))We need to find the values of A, B, and C.
Clear fractions: Multiply both sides by the denominator to clear the fractions.Multiplying both sides by (2x−1)2, we get:8x2−6x+3=A(2x−1)2+B(2x−1)+C
Expand right side: Expand the right side of the equation.Expanding A(2x−1)2 and B(2x−1), we get:8x2−6x+3=A(4x2−4x+1)+B(2x−1)+C
Equate coefficients: Equate the coefficients of like terms on both sides of the equation.For the x2 terms: 8=4AFor the x terms: −6=−4A+2BFor the constant terms: 3=A−B+C
Solve for A: Solve for A from the x2 terms.Dividing both sides by 4, we get A=2.
Solve for B: Substitute A into the equation for the x terms and solve for B.−6=−4(2)+2B−6=−8+2B2B=2B=1
Solve for C: Substitute A and B into the equation for the constant terms and solve for C.3=2−1+CC=3−2+1C=2
