Using the discriminant of b^2 -4ac = 0 the value of k works out as -2

Using the discriminant the possible values of k are -9 or 9

Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.

If the discriminant of a quadratic equal is zero then it will have two equal roots.

That is not an equation, since it doesn't have an equal sign.

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.

It is a quadratic equation in X, with two real roots.

25 squared plus 49 squared is equal to 3,026.

12 squared plus 18 squared is equal to 468.

6 squared plus 9 squared is equal to 117.

No because no 2 numbers can be squared to equal 4. 1 squared is 1 2 squared is 4 so the lowest answer is 5.
