Q. Simplify the rational expression: \newline2q2qr3r22q29qr+9r2\frac{2q^{2}-qr-3r^{2}}{2q^{2}-9qr+9r^{2}}\newlineA) (q+r)/(k+3r)(q+r)/(k+3r)\newlineB) Cannot be simplified\newlineC) (a+r)(q3r)(a+r)(q-3r)\newlineD) (q+r)(q+3r)(q+r)(q+3r)
  1. Factor Numerator: Factor the numerator 2q2qr3r22q^2 - qr - 3r^2.\newline2q2qr3r2=(2q+3r)(qr)2q^2 - qr - 3r^2 = (2q + 3r)(q - r)
  2. Factor Denominator: Factor the denominator 2q29qr+9r22q^2 - 9qr + 9r^2.\newline2q29qr+9r2=(q3r)(2q3r)2q^2 - 9qr + 9r^2 = (q - 3r)(2q - 3r)
  3. Write Expression: Now, write the expression with factored numerator and denominator.\newline(2q+3r)(qr)÷(q3r)(2q3r)(2q + 3r)(q - r) \div (q - 3r)(2q - 3r)
  4. Cancel Common Factors: Cancel out the common factors.\newlineThere are no common factors to cancel out.
