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.
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)
(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.
A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
= (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
2ab
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
(a+b)(a+b)Also equal to a2+2ab+b2
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
To factorize the expression 4ab - 6ab, you first need to identify the common factor between the two terms, which is 2ab. You can then factor out this common factor to rewrite the expression as 2ab(2 - 3). Therefore, the fully factorized form of 4ab - 6ab is 2ab(2 - 3) or simply -2ab.
(a-b)^2 doesn't have a numeric value since there are no numbers associated with it, but you can definitely expand it, as it represents a formula, instead of an actual numeric expression.(a-b)(a-b)= a^2-ab-ab+b^2= a^2-2ab+b^2 (which is actually the rule for expanding!)
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)
x=ab
