Question

a) [1/2a+3]²

b) [3x-1/6]²

c) [1+x/3] [1-x/3]

d) [m/2+5/3]

ALGUEM PODE ME AJUDAR POR FAVOR

Answer 1

a)(1/2a+3)^2
(1/2a)^2+2(1/2a)(3)+(3)^2
1/4a^2+6a/2+9
1/4a^2+3a+9
b)(3x-1/6)^2
(3x)^2-2(3x)(1/6)+(1/6)^2
9x^2-6x/6-1/36
9x^2-x-1/36
c)(1+x/3)(1-3x)
1-x/3+x/3;x^2/9
1-x^2/9
d)(m/2+5/3)^2
(m/2)^2+2(m/2)(5/3)+(5/3)^2
m^2/4+5/3m+25/9
