See explanation.

To find a product of 2 algebraic sums you have to multiply each term of one sum by each term of the other and then reduce the like terms.

$(u + 3) (u - 3) = u^{2} - 3 u + 3 u - 9 = u^{2} - 9$ $(u+3)(u-3)=u^2-3u+3u-9=u^2-9$

How do you find the product (u+3)(u-3)(u+3)(u−3)(u+3)(u-3)?
