Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
It is an equation and the value of n is 9
This is a simultaneous equation question: x-2y = -4 2x-y = 1 Multiply all terms in the top equation by 2: 2x-4y = -8 2x-y = 1 Subtract the bottom equation from the top equation remembering that a minus minus equals a plus: -3y = -9 Divide both sides of the equation by -3 to find the value of y remembering that a minus divided by a minus equals a plus: y = 3 Substitute the value of y into the original equations to find the value of x: Solution: x = 2 and y = 3
It is a quadratic equation and the value of x is -7 or 6 x2 - 42 = (-x) x2 + x - 42 = 0 (x + 7) (x - 6) = 0

The equation does not have a real number solution. Using the quadratic formula will give it's conjugate pair complex solution.

You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
Choose any value for "x", replace that in the equation, and calculate the corresponding value for "y".
Using the quadratic equation formula the value of x is -8 or 5
a=64 b=8 (x+16x+64)=(x+8)^2
-6 when you multiply two minus numbers the minus signs cancel each other out so -12 * -6 = 72
