Make 'b' a negative number with a higher absolute value than 'a' - for example, a = 4 and b = -5. Then b2 will always be greater than a2.

Sum and difference of two cubes?
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2
Factor a perfect square?
To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
What is the pattern of sum of cubes?
(a3 + b3) = (a + b)(a2 - ab + b2)
Sum of two cubes?
a3+ b3 = (a + b)(a2 - ab + b2)
How do you factor y2-64?
y2 - 64 can be written as y2 - 82, which is of the form of a2 - b2.And a2 - b2 is factored as (a-b)(a+b).Therefore, y2 - 64 is factored as (y+8)(y-8).
What is the proof that a and b are positive numbers and a is greater than b then a squared is greater than b squared?
One way to prove this is as follows: Given a > b and a>0 and b>0 Define a new constant 'n' such that a - b = n then a2 = (b + n)2 a2 = b2 + 2bn + n2 since b and n are both positive, 2bn is a positive value and n2 is also positive So a2 > b2 because a2 - 2bn - n2 = b2
How do you calculate in Excel commission of 7 percent on all sales that are at least 25 percent above cost?
Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )Assuming the sale is in B2 and the cost in A2, you could use the following formula to do it:=IF( B2>=A2*1.25, B2*7%, 0 )
What are the different ways to show the pythagorean theorem?
They are: a2+b2 = c2 c2-a2 = b2 c2-b2 = a2
Why the square of the sum of two numbers is different from the sum of the squares of two numbers?
call the numbers a & b (a+b)2 = a2+2ab+b2 which is greater than a2 + b2 by twice the product of the numbers. Check: say 3 and 5 32 + 52 = 9 + 25 = 34 (3 +5)2 = 64, greater by twice a x b. QED -------------------- If a and b are the numbers, then (a+b)2 = a2 + 2ab + b2, which is different from a2 + b2 (not necessarily larger). The two quantities are equal only when one (or both) of a,b is zero.
How do you calucate a2 plus b2?
a2+2a2b+2ab2+b2
How do you rearrange v squared equals b squared bracket a squared - x squared bracket to make x the subject?
v2 = b2 (a2 - x2)Divide each side by b2 :v2/b2 = a2 - x2Subtract a2 from each side:v2/b2 - a2 = -x2Multiply each side by -1 :x2 = a2 - v2/b2Take the square root of each side:x = ± sqrt ( a2 - v2/b2 )
How would you factor the polynomial a2-b2?
a2-b2 = (a-b)(a+b)
What is A2 b2 c2?
If you are talking about a2+b2=c2 then that is Pythagorean theorem.
What is the formula for - tell cell B that if cell A empty leave cell B blank and if cell A is greater than 1 make cell B say Hours?
Your formula is not complete as you do not say what happens if the A cell contains 1 and is therefore not bland and not over 1. Using cells A2 and B2 the formula would be put into cell B2 and would be: =IF(A2="","",IF(A2>1,"Hours",""))
If a2 plus b2 equals c2 then c2 equals b2 equals?
a2
How do you find B squared in Pythagorean theorem?
C2=A2+B2 Therefore to find B2: B2=C2-A2
What are the types of Pythagorean theorem?
The Pythagorean theorem is a2 + b2 = c2
