A(b+c)=ab+ac
a is gcf

9=3*3
36=2*2*3*3
gcf=3*3=9

a=9
36/9=4

revers
ab+ac=a(b+c)
9(1)+9(4)=9(1+4)=9(5)=45

Find the square: (5x - 4y)2 (and please put the process of solving the equation)

satela [25.4K]

$(5x-4y)^2$
$(5x-4y)(5x-4y)$

Multiply each term in one bracket in turn by the terms in the other bracket

$(5x)(5x) = 25x^2$
$(5x)(-4y)=-20xy$
$(-4y)(5x)=-20xy$
$(-4y)(-4y)=16y^2$

Put them together we have
$25x^2-20xy-20xy-16y^2$
$25x^2-40xy-16y^2$
