expand (2x-3y)(x-5y)

Assessment: WAEC SSCE - General Mathematics - 2005 (Objective) Subject: General Mathematics

Question 1 Report

expand (2x-3y)(x-5y)
Answer Details
To expand (2x-3y)(x-5y), we use the distributive property of multiplication, which states that a(b+c) = ab + ac. Applying this property, we get: (2x-3y)(x-5y) = 2x(x-5y) - 3y(x-5y) = 2x^2 - 10xy - 3xy + 15y^2 = 2x^2 - 13xy + 15y^2 Therefore, the answer is (2x^2 - 13xy + 15y^2).
