Question

desenvolva cada quadrado da soma a seguir

Answer 1

a)=(x+3)²= x²+2.x.3+3²⇒ x²+6x+9

b=(x+3/4)²= x²+ 2.x.3/4+(3/4)²⇒ x²+6/4x+9/16

c=(2a+b)2=(2a)²+2.2a.b+b²⇒ 4a²+4ab+b²

d=(x+3y)²=x²+2.x.3y+(3y)²⇒x²+6xy+9y²

e)(x²+4)²= (x²)²+2.x².4+4²⇒ x^4+8x²+16

f) (a+√5)²= a²+2.a.√5+(√5)²⇒ a²+2a√5+5

g) ( x³+3)²= (x³)²+2.x³.3+3²⇒ x^6+6x³+9

h)( 10x+2t²)²= (10x)²+2.10x.2t²+(2t²)²⇒100x²+40xt²+4t^4
