Answer 1

(a+b)² = (a + b)(a + b) = a² + 2ab + b²
<>>

Answer 2

as far as i know, you mean (a+b)^2

that is (a+b) multiplied by (a+b)

so, we get,
=(a+b)(a+b)
=a^2+ab+ab+b^2
=a^2+2ab+b^2

to find the square of a number, this is used for ease, suppose we have to find the square of 101, we write 101 in the a+b form

we can write it as: 99+2
98+3
but, we use 100+1(because it is easier to add, subtract, multiply or divide any number by 100 and by 1)

so, the square of 101(square means multiplying a number by itself) is:

(100+1)^2
=(100+1)(100+1)
=(100)^2+100+100+1
=10000+100+100+1 (to multiply a number by hundred, just put 2 zeroes in front of it.. like 9 x100=900)
=10201

Answer 3

2a+2b

but if u mean squared, its
a^2+b^2+2ab

Answer 4

(a+b)^2 use FOIL
a^2+ab+ab+b^2
a^2+2ab+b^2

Answer 5

(a + b)2

By the distributive law, this is equal to

2a + 2b

Not sure if that's the answer you're looking for.

Answer 6

(a+b)^2
=(a+b)(a+b)
=a^2+ab+ba+b^2
=a^2+2ab+b^2

Answer 7

Do you mean (a+b)square or (a+b)*2?
If it is(a+b)square
a square+b square+2ab
If it is(a+b)*2
2a+2b

Answer 8

how about 2(pts)
