Answer:
[tex](2x+10)^2=4x^2+40x+100[/tex]
Step-by-step explanation:
Given the expression
[tex](2x+10)^2[/tex]
we have to simplify the above expression.
By identity
[tex](a+b)^2=a^2+2ab+b^2[/tex]
Put a=2x and b=10
[tex](2x+10)^2=(2x)^2+2(2x)(10)+10^2[/tex]
[tex](2x+10)^2=4x^2+40x+100[/tex]
Option B is correct.
