What is the geometrical proof of a-b whole square?
Given the graphic capability of this site, you are going to have to use some imagination! <---------a---------> <---a-b---><--b--> +-----------+-------+ |...............|..........| |.......P......|....Q...| |...............|..........| +-----------+-------+ |.......R......|....S....| |...............|..........| +-----------+-------+ In the above graphic, P, S and the whole figure are meant to be squares. The total area is P+Q+R+S = a2 P = (a-b)2 Q = b*(a-b) = (a-b)*b = a*b - b2 R = (a-b)*b = a*b = a*b - b2 and S = b2 Now, P = {P+Q+R+S} - Q - R - S = a2 - ab + b2 - ab + b2 - b2 = a2 - 2ab + b2
What is the answer for b2 plus 16b plus 64?
b2 + 16b + 64 can be factorized to (b+8)(b+8). If they were equal to zero as in b2 + 16b + 64=0 then b = -8.
What is b2-2b plus 3b-6?
The equation (b2 - 2b) + (3b - 6) = b2 + b - 6
What is a x squared plus b x plus c equals 0?
x = (-b (+/-) root( b2 - 4ac)) / 2a Sorry about the messy answer, there are no square root symbols or plus-minus symbols. Here is the proof - ax2 + bx + c = 0 --------> multiply by 4a 4a2x2 + 4abx + 4ac = 0 4a2x2 + 4abx = -4ac ----------> add b2 to both sides 4a2x2 + 4abx + b2 = b2 - 4ac -----------> factorise LHS (2ax + b)2 = b2 - 4ac 2ax + b = (+/-) root( b2 - 4ac) 2ax = -b (+/-) root( b2 - 4ac) x = (-b (+/-) root( b2 - 4ac)) / 2a Maths works people.
What is the form of the sum of cubes identity?
a3 + b3 = (a + b)*(a2 - ab + b2)anda3 - b3 = (a - b)*(a2 + ab + b2)
What is the greatest common factor of a3b and a2b2?
The GCF is a2b.
What is the GCF of 5 ab and 6 b2?
b
Find the gcf of 27 ab and 81 b 2?
The GCF is 27b.
What is the gcf of 50 a b2 c3 and 50 a b c?
Since 50abc is a factor of 50ab2c3, it is automatically the GCF.
What is the GCF of 20b3 15b2 and 18b5?
The GCF is b2.
What is the GCF of 8a2b and 14a b2?
The GCF is 2ab.
How would you factor the polynomial a2-b2?
a2-b2 = (a-b)(a+b)
Evaluate a ba2 - ab b2 when a -3 and b -2?
B2 for B = 9.
When a polynomial has two terms how many methods might be used for factoring it?
Step 1. Look for a GCF. Step 2. Look for the difference of squares. ex: a2 - b2 = (a+b)(a-b) Step 3a. Look for the difference of cubes. ex: a3 - b3 = (a-b)(a2 + ab + b2) Step 3b. Look for the sum of cubes. ex: a3 + b3 = (a+b)(a2 - ab + b2)
What is b times b?
b2
