Question

a) (2x+4)²
b) (x-8)²
c) (3x+2)²
d) (5x-3)²
e) (x+5)²​

Answer 1

Explicación paso a paso:

a) (2x+4)²

= (2x)²+2•2x•4+4²

= 4x²+4x•4+16

= 4x²+16x+16

b) (x-8)²

= x²-2x•8+8²

= x²-16x+64

c) (3x+2)²

= (3x)²+2•3x•2+2²

= 9x²+6x•2+4

= 9x²+12x+4

d) (5x-3)²

= (5x)²-2•5x•3+3²

= 5x²-10x•3+9

= 25x²-30x+9

e) (x+5)²

= x²+2x•5+5²

= x²+10x+25

espero te ayude:)
