(a*+2)*...................?

Question

*= squared

if just not sure what to do when you get to the poing of combining like terms

ill get u started


(a*+2)(a*+2)

just multiply these

for other exponents, just do this (^#)

thanks

Answer 1

(a^2+2)(a^2+2)

First: eliminate parenthesis - use the Foil Method.

(a^2)(a^2)+(a^2)(2)+(2)(a^2)+(2)(2)

*Rule - when you multiply terms with the same variable - always add exponents.

a^4 + 2a^2 + 2a^2 + 4

SEc: combine "like" terms - combine terms with the same variable.

a^4 + 4a^2 + 4

Answer 2

(a²+2)²

Okay, doing this the long way:

(a²+2)(a²+2)

Using the distributive property once:

a²(a² +2) + 2(a²+2)

And twice:

a⁴ + 2a² + 2a² + 4

Combining like terms:

a⁴ + 4a² + 4

And we are done.

Answer 3

a^4+4a^2+4

Answer 4

(a*+2)(a*+2)
a*+2(a*+2)
a*+2a*+4
3a*+4
