(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!)

Isosceles trapezoid abcd has an area of 276 in squared if ad equals 13 inches and de equals 12 inches find ab?
Isosceles trapezoid ABCD has an area of 276 If AD = 13 inches and DE = 12 inches, find AB.
In circle O the area of the sector with central angle AOB is 30 pi cm squared and radius OA is 6 cm. What is the angle measure of arc AB and the length of AB?
The area of the whole circle is PI x 6 squared which equals 36 PI. We can now use the ratio 30/36 = x/360 to find the angle (360 is the full angle if the circle, x is the angle of the segment, pi's cancell out) If we solve for x we get 300 degrees which is the angle we need. As for the length, the circles circumference is 12 PI (12 is the diameter). This means that 30/36= AB/12PI AB=10PI
How many meters squared in 100cm squared?
100cm squared = 0.01 metres squared
If ab then ba?
If these are vectors, then ba = - ab
Is ab squared the same as 2ab?
ab(ab) =2ab
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 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.
Factor a cubed plus B-Cubed?
(a+b)(a squared-ab+b squared)
What is the area of square AB?
The length of its side squared.
A B and C are all squared numbers. A b also a c and b c make squared numbers what are A B and c?
ab x ac = ab - ac
Factor x squared y squared plus ay squared plus ab plus bx squared?
(a + x^2)(b + y^2)
What does this equal to 12a squared b squared - 144ab?
-132
What is the answer when Ab is not equal to 0 -12a cubed times b squared over 6ab squared?
-2a^2
Factor X squared y plus axy plus abx plus a squared b?
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
Why does b times ab equal ab squared and not equal ab plus b squared?
b*ab = ab2 Suppose b*ab = ab + b2. Assume a and b are non-zero integers. Then ab2 = ab + b2 b = 1 + b/a would have to be true for all b. Counter-example: b = 2; a = 3 b(ab) = 2(3)(2) = 12 = ab2 = (4)(3) ab + b2 = (2)(3) + (2) = 10 but 10 does not = 12. Contradiction. So it cannot be the case that b = 1 + b/a is true for all b and, therefore, b*ab does not = ab + b2
