Answer:
Solution,
( 5x - 3y) ( 3x +4y)
Multiply each terms in the first parentheses by each term in the second paranthesis.
5x * 3x + 5x * 4y - 3y * 3x - 3y * 4y
Calculate the product
15x^2 + 20xy -9xy -12y^2
Collect like terms and simplify
15x^2 + 11xy -12y^2
Hope this helps...
Good luck on your assignment...
