Use the distributive property to multiply one binomial by the other binomial and combine like terms.

Explanation:

# (5y -4) xx (3y -1) = 5y(3y-1 )- 4(3y -1) # Now multiply across the parenthesis

# 5y(3y-1) - 4(3y -1) = 15y^2 - 5y - 12y + 4 # combining like terms gives

# 15y^2 + ( -5y -12y) + 4 = 15^2 - 17y + 4#
