Class 8MathematicsAlgebraic Expressions and Identities
Multiplying Expressions
Monomial × monomial: multiply coefficients and add powers. 3x² × 4x³ = 12x⁵. Monomial × binomial: distributive property. 2x(x+3) = 2x²+6x. Binomial × binomial: FOIL (First, Outer, Inner, Last). (x+3)(x+4) = x²+4x+3x+12 = x²+7x+12.
