What is the root of a quadratic equation?
The roots are (if the equation is of the form Ax2 + Bx + C = 0 ((-B) + Square Root of (B2 - 4xAxC)) / 2xA and ((-B) - Square Root of (B2 - 4xAxC)) / 2xA
What is the quadratic formula of algebra?
(−b±√b2−4ac)÷2a the square root of b2−4ac entirely.
How di you find the hypontnuse if a the square root of3 and b the square root of5?
If it's a right triangle, a2 + b2 = c2 3 + 5 = c2 c = the square root of 8.
How do you find A in the pythagorean theorem?
a2 + b2 = c2 a2 = c2 - b2 a = sqrt(c2 - b2) ==================no +/- square root as a negative length makes no sense in a right triangle
What is the disciminant in the equation z2-4z plus 4 equals 0?
quadratics have the form ax2+bx+c=0 the discriminant is the square root of (b2-4ac) = square root of (16-16) =square root of 0 = 0

(−b±√b2−4ac)÷2a the square root of b2−4ac entirely.
What is the square root of a squared plus b squared?
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
Can you simplify the square root of a2 plus b2?
Cannot be simplified
What is the value of diagonal of rectangle?
It is square root of (length square + breadth square) (l2 + b2 ) 1/2
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 length of a of one side of a triangle?
Assuming that you are talking about a right triangle. a2 + b2 = c2 Solve for a a = square root of c2-b2
Distance around a triangle?
You can use the Pythagorean Theorem to find the distance around a right triangle. The equation for this is a2 = b2 + c2. Further through the equation, it is a = square root of b2 +c2. If you know one side of the right triangle is 4 and a second side is 6, the equation would be as follows. a2 = b2 + c2 a = square root of 42 + 62 a = square root of 16 + 36 a = square root of 52 a = 7.211
How can you use the converse of the pythagorean theorem to tell whether three given lengths can be sides of triangles?
* To find the hypotenuse, take the square root of (a2 + b2). * To find either of the two shorter sides, take the square root of (c2 - b2)
