What is (x + 2)(x + 2)?
just expand using the distributive property
(x+2)(x+2)
x^2 + 2x + 2x + 4
= x^2 + 4x + 4
memorize (a+b)^2 = a^2 + 2ab + b^2
Hey thanks again mathhelper (yes I am the same person, you might remember me from 1 year ago)
If you are evaluating it is this:
(x+2)(x+2)
Multiply x+2 and x+2 to get (x+2)^2
(x+2)^2
Use binomial theorem (a+b)^2=a^2+2ab+b^2 to expand (x+2)^2.
x^2+4x+4
If you are expanding it is this:
(x+2)(x+2)
Multiply x+2 and x+2 to get (x+2)^2
(x+2)^2
Use binomial theorem (a+b)^2=a^2+2ab+b^2 to expand (x+2)^2
x^2+4x+4
Hope this helps!! Sorry it took so long.
No its all right (Yes, my initial name was "Kind of stressed out")
Oh! How interesting anyways have a good day!
Yes have a good day! (We shall meet again in the next latest question)
To find the product of (x + 2)(x + 2), you can use the distributive property. The distributive property states that for any three numbers a, b, and c, the product of (a + b) and c is equal to the product of a and c plus the product of b and c. In this case, a is x, b is 2, and c is (x + 2).
So, using the distributive property, we can write:
(x + 2)(x + 2) = x(x + 2) + 2(x + 2)
Now, we can apply the distributive property again to expand each term further:
= x * x + x * 2 + 2 * x + 2 * 2
Simplifying each term:
= x^2 + 2x + 2x + 4
Combining like terms:
= x^2 + 4x + 4
Therefore, (x + 2)(x + 2) simplifies to x^2 + 4x + 4.
