Question 164907
(2x-5y)(7x+3y)  multiply each term on the right by 1st term on left giving you 14x^2+6xy  then multiply each term on the right by the 2nd term on the left giving you -35xy-15y^2 combining like terms you get 14x^2-29xy-15y^2   so that is 14x(squared)-29xy-15y(squared) just in case you are unfamiliar with the ^ sign.
