Question

Expand: (4x - 3y + 22)2​

Answer 1

(4x-3y+22)²

(4x-3y+22)(4x-3y+22)

4x(4x-3y+22)-3y(4x-3y+22)+22(4x-3y+22)

16x²-12xy+88x-12xy+9y²-66y+88x-66y+4

84

16x²+9y²-12xy-12xy+88x+88x-66y-66y+484

16x²+9y²-24xy+176x-132y+484

Answer 2

Hey, here is your answer.....

$(4x-3y+22)^{2} = 4x^{2} +9y^{2} +484 -2(4x)(3y) -2(3y)(22) + 2(4x)(22)\\\\(4x-3y+22)^{2} = 4x^{2} +9y^{2} +484 -24xy -132y +176x$

Hope this helps you.......
