= (a + b)2 or (a + b)(a + b)

(a + b)(a + b) using the FOIL method yields:

[multiplying {First Outer Inner Last} and summing the products]

= a.a + a.b + b.a + b.b

= a2 + ab + ab + b2

= a2 + 2ab + b2

What does a squared plus b squared equal?

(a+b)(a+b)Also equal to a2+2ab+b2


Is a squared plus b squared the same as a plus b squared?

No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2


How do you factor perfect square binomial?

Remember to factor out the GCF of the coefficients if there is one. A perfect square binomial will always follow the pattern a squared plus or minus 2ab plus b squared. If it's plus 2ab, that factors to (a + b)(a + b) If it's minus 2ab, that factors to (a - b)(a - b)


How do you factor a times a cubed plus 2 times a times b plus b squared?

the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)


What is 12a squared b plus 6a?

12a2b + 6a = 6a(2ab + 1)


For what numbers is the following equation true a plus b squared is equal to a squared plus b squared?

(a + b)² = a² + b². If you expand the left side, you have a² + 2ab + b² = a² + b². Subtracting a² and b² from both sides, you have: 2ab = 0. So if either a=0 or b=0 the equation is satisfied.


What is the equation for a b whole square?

(a+b)^2=a^2+b^2+2ab it should read "the quanitity "a plus b" squared equals a squared plus b squared plus two a times b" See related link below for a picture that shows it graphically.


What is b squared plus ab minus two minus two b squared plus two ab?

b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.


Show a plus b divided 2 equals 2ab divided by a plus b?

b/2=2ab/+b means112.5


Is ab squared the same as 2ab?

No, ab squared is not the same as 2ab. ab squared (ab^2) means multiplying ab by itself, resulting in a^2 * b^2. On the other hand, 2ab means multiplying 2 by a and then by b, resulting in 2ab. These two expressions are not equivalent because ab^2 involves squaring the variable b, while 2ab does not involve squaring any variables.


What is A B squared?

A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2


What is 5ab plus 4a-b-2ab plus 5b?

5ab-2ab+4a-b+5b = 3ab+4a+4b
