Question

expand the following (x+5y+6z)^2​

Answer 1

Answer:

x^2 + 25y^2 + 36z^2 + 10xy + 60yz + 12xz

Step-by-step explanation:

(x+5y+6z)^2

(a+b+c)^2 =a^2 + b^2+c^2+2ab+2bc+2ac

a= x , b= 5y , c= 6z

(x+5y+6z)^2 = x^2+(5y)^2+(6z)^2+ 2(x)(5y)+2(5y)(6z)+2(6z)

= (x)

= x^2 + 25y^2 + 36z^2 + 10xy + 60yz + 12xz

Answer 2

Hi friend!

Here is your answer!

(x+5y+6z)^2

{Applying (a+b+c)^2}

(x+5y+6z)^2

=x^2 + (5y)^2 + (6z)^2 + 2(x)(5y) + 2(5y)(6z) + 2(6z)(x)

=x^2 + 25y^2 + 36z^2 + 10xy + 60yz + 12zx

Hope this helps!!

Thanks!!
