Consider the product (x + y + z)2. if the expression is multiplied out and like terms collected, the result is: x2 + y2 + z2 + 2xy + 2yz + 2xz suppose we do the same to the product (v + w + x + y + z)25 (a) what is the coefficient of the term v9w2x5y7z2? (b) how many different terms are there? (two terms are the same if the degree of each variable is the same.)

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
