To evaluate it you need to know both b and a. But it is possible to factorise it as follows:

b2-a2 = (b-a)*(b+a)

B squared equals c squared minus a squared then to find B take the square root of you answer for b squared

If a equals 3 and b equals minus 5 then a minus b equals what

x equals negative b plus or minus the square root of b squared minus 4bc over 2a

The formula for finding the angles is called " Pythagorean Thyrum " It states that a squred plus b squared equals c squared so therefore c squared minus a squared will equal b squared. i hope that helps

It is: (B -10)(B +10) when factored

A - B = 11A = 11 + whatever ' B ' is.

Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.

you use A squared plus B squared equals C squared

The Quadratic Formula song: (my grade saver) To the tune of the jack in the box song X equals negative B plus or minus square root of B squared minus 4AC all over 2A :)

x = -4 The equation to find this is -b/2a with 8 being the b and 1 being the a.

If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A

72 minus the root of squared minus equals 72 but you have to be smart to know that the minimum circumference s 56 there you go

I suggest you use the quadratic formula, with a = 3, b = -2, c = 7.

The solution follows A=42 42X42=1764 B=56 56X56=3136 sum of above=4900 (70X70=4900) Given you was looking for C and not C squared. Try A and B and doublecheck it for me.
