Q. −20x2+25x2y−40x=−5x(4x−5xy+c)What is the value of c?
Distribute Terms: Distribute −5x across the terms inside the parentheses on the right side of the equation.−5x×4x=−20x2−5x×−5xy=25x2y−5x×c=−5xc
Compare Distributed Terms: Compare the distributed terms with the corresponding terms on the left side of the equation.The term −20x2 on the left matches the term −20x2 on the right.The term 25x2y on the left matches the term 25x2y on the right.The term −40x on the left should match the term −5xc on the right.
Set Equation Equal: Set the unmatched terms equal to each other to solve for c.−40x=−5xc
Divide to Solve: Divide both sides of the equation by −5x to solve for c.c=−5x−40x
Simplify for c: Simplify the equation to find the value of c.c=8
