If a2 plus b2 equals c2 then c2 equals b2 equals?
a2
What is the reciprocal of a plus bi if a2 plus b2 equals 1?
The reciprocal of a + bi is a - bi:1/(a + bi) since the conjugate is a - bi:= 1(a - bi)/[(a + bi)(a - bi)]= (a - bi)/[a2 - (b2)(i2)] since i2 equals to -1:= (a - bi)/(a2 + b2) since a2 + b2 = 1:= a - bi/1= a - bi
Can you simplify the square root of a2 plus b2?
Cannot be simplified
A2 plus b2 equals c2 is an example of?
Pythagorean Theorem
If a2 plus b2 equals c2 then the triangle is?
a right triangle
Factor A2 plus 4a plus 4 - b2?

How would you factor the polynomial a2-b2?
a2-b2 = (a-b)(a+b)
How do you calucate a2 plus b2?
a2+2a2b+2ab2+b2
If a2 plus b2 equals c2 then c2 equals b2 equals?
a2
How do you factor b squared plus two?
as a2+b2=(a+ib)(a-ib), b2+2=[b - i sqrt(2)] [b + i sqrt(2)]
How would you factor A2-B2?
(a + b)(a - b)
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
Why is the Pythagorean therm a2 plus b2 equals c2 not a plus b equals c?
l a2 b2 is c2!!Its completely norma
How do you simplify the square root of a squared plus b squared?
sqrt(a2 + b2) can't be simplified. Neither can (a2 + b2) .
How do you factor a difference of squares?
a2-b2=(a-b)(a+b)
What is the reciprocal of a plus bi if a2 plus b2 equals 1?
The reciprocal of a + bi is a - bi:1/(a + bi) since the conjugate is a - bi:= 1(a - bi)/[(a + bi)(a - bi)]= (a - bi)/[a2 - (b2)(i2)] since i2 equals to -1:= (a - bi)/(a2 + b2) since a2 + b2 = 1:= a - bi/1= a - bi
How do you factor the sum and difference of two cubes?
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
