(m + 2p)² =

(2x + 7y)² =

são contas separadas, urgente

Answer 1

$(8x + 1)^2\\\left(8x\right)^2+2\cdot \:8x\cdot \:1+1^2\\64x^2+16x+1$

$\left(m+2p\right)^2\\{x}^2+2m\cdot \:2p+\left(2p\right)^2\\m^2+4mp+4p^2$

$\left(2x+7y\right)^2\\\left(2x\right)^2+2\cdot \:2x\cdot \:7y+\left(7y\right)^2\\4x^2+28xy+49y^2$
