$x^2 - 6xy + 9y^2$

Work Step by Step

$Multiply$ $the$ $algebraic$ $expressions$ $using$ $a$ $Special$ $Product$ $Formula$ $and$ $simplify:$ $(x-3y)^2$ Use the Square of a Difference Product Formula: $(A-B)^2 = A^2 - 2AB + B^2$ $(x-3y)^2$ = $x^2 - (2\times x\times 3y) + (3y)^2$ $= x^2 - 6xy + 9y^2$
