find the value of the expression

Question

find the value of the expression a²+2ab+b² if a=6 and b=4

Answer 1

there is an easier way

the expression a2 +2ab + b2 is equivalent to

(a+b)squared = 10 squared = 100

Answer 2

Carissa,

Since you are given the values of a and b, all you need to do to solve this would be to plug in the numbers into the given expression then solve.

So start by plugging in for a and b.

6²+2(6)(4)+4²

Now we can solve, starting with parenthesis/exponents from left to right:

36+2(6)(4)+16

Then multiplication/division from left to right:

36+48+16

Then addition/subtraction from left to right:

=100
