Identify Given Expression: Identify the given expression and look for common denominators in the numerator and the denominator to combine terms.The expression is (5x2−x)/(9x+31)
Combine Common Denominators: Combine the terms in the denominator by finding a common denominator.The common denominator for (9x) and (31) is 9.So, (9x)+(31) becomes (9x)+(93) which simplifies to (9x+3).
Rewrite with Simplified Denominator: Rewrite the expression with the simplified denominator.The expression now is (5x2−x)/(9x+3).
Multiply by Least Common Multiple: To simplify the complex fraction, multiply the numerator and the denominator by the least common multiple (LCM) of the denominators inside the complex fraction, which is 45. So, we multiply (5x2−x) and (9x+3) by 4545.
Multiply Numerator by 45: Multiply the terms in the numerator by 45.(x2/5)⋅45=9x2 and −x⋅45=−45x.So, the numerator becomes 9x2−45x.
Multiply Denominator by 45: Multiply the terms in the denominator by 45. 9x+3×45=5(x+3).So, the denominator becomes 5(x+3).
Rewrite with Multiplied Numerator/Denominator: Rewrite the expression with the multiplied numerator and denominator.The expression now is (9x2−45x)/(5(x+3)).
Factor Out Common Factor: Factor out the common factor in the numerator.The common factor is 9x, so factor it out to get 9x(x−5).The expression now is 5(x+3)9x(x−5).
Check for Common Factors: Check for any common factors that can be canceled out from the numerator and the denominator.There are no common factors to cancel out between 9x(x−5) and 5(x+3).
