How do you calucate a2 plus b2?

If a2 plus b2 equals c2 then c2 equals b2 equals?

a2

Factor A2 plus 4a plus 4 - b2?

a2 - 4a + 4

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) .

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

What are the lengths of and A plus B in a right triangle if C equals 8?

A2 + B2 = C2 If C=8, then A2 + B2 = 64

How do you solve a to the 3rd power plus b to the 3rd power divided by a plus b?

(a3 + b3)/(a + b) = (a + b)*(a2 - ab + b2)/(a + b) = (a2 - ab + b2)

If a plus b plus c equals x plus y plus z then prove a2 plus b2 plus c2 equals x2 plus y2 plus z2?

a2+b2+c2=x2+y2+z2 divide each side by 2 (a2+b2+c2)/2=(x2+y2+z2)/2 a+b+c=x+y+z

What is the formula of a2 plus b2 plus c2?

It is a*a + b*b + c*c

How do you calculate in Excel commission of 7 percent on all sales that are at least 25 percent above cost?
