Question

efetue c)(a+3x)elevado a 2, d)(10x+y)elevado a dois, e)(5x elevado a 2 +1)elevado a 2, f)(11+pq)elevado a 2,g)(x+0,5)elevado a 2 ,h)(x+1/2)elevado a 2

Answer 1

(a+3x)²=a²+2*a*3x+(3x)²=a²+6ax+9x²

(10x+y)²=(10x)²+2*10x*y+y²=100x²+20xy+y²

(5x²+¹)²=25x^6

(11+pq)²=11²+2*11*pq+(pq)²=121+22pq+p²q²

(x+0,5)²=x²+2*x*0,5+(0,5)²=x²+1x+0,25

(x+1/2)²=x²+2*x*1/2+(1/2)²=x²+2x/2+1,44
