Study Notes

Simplifying Rational Expressions

  • Simplify rational expressions by combining like terms and canceling out common factors.
  • Examples: 16m^2/24m, 3x^2 - 10x - 24/x+2, etc.

Multiplying Rational Expressions

  • Multiply rational expressions by multiplying the numerators and denominators separately.
  • Examples: (32x^3y)/(15y) × (5xy^2)/(8x^2y^4), (28n+40)/(12n+24) × (35n+50)/(8n+16), etc.

Dividing Rational Expressions

  • Divide rational expressions by inverting the second expression and then multiplying.
  • Examples: (14m^2)/(7m) ÷ (3m)/(18m^5), (2a+14a)/(10a+70) ÷ (8a^2), etc.

Product of Rational Expressions

  • Find the product of rational expressions by multiplying the numerators and denominators separately.
  • Examples: (32x^3y)/(15y) × (5xy^2)/(8x^2y^4), (28n+40)/(12n+24) × (35n+50)/(8n+16), etc.

Quotient of Rational Expressions

  • Find the quotient of rational expressions by inverting the second expression and then multiplying.
  • Examples: (14m^2)/(7m) ÷ (3m)/(18m^5), (2a+14a)/(10a+70) ÷ (8a^2), etc.
