How do you work out what x and y are equal to using x squared plus y squared equals 25 and y equals 3x plus 1?
since y = 3x+1 we have
y squared =(3x+1) squared
x^2 + y^2 = 25
x^2 + (3x+1)^2=25
x^2 + 9x^2+ 6x+1 = 25
10x^2 + 6x + 1 = 25
10x^2 + 6x -24 = 0
solve x from quadratic formula
x = 1.28
y = 3x + 1 = 4.83

What is the value of k when the equation x squared plus 2kx plus 10x plus k squared plus 5 equals 0 has equal roots?
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
A squared plus b squared equals c squared?
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
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.
What are the possible values of k when the equation x squared plus 2kx plus 81 equals 0 has equal roots?
Using the discriminant the possible values of k are -9 or 9
