x2+2x+x0 = 0
Any integer raised to the power of 0 is always 1 so the equation can be arranged as:
x2+2x+1 = 0
When factorised:
(x+1)(x+1) = 0
Therefore: x = -1 and also x = -1
They both have equal roots because the discriminant b2-4ac (22-4*1*1) = 0

no
What is X squared equals 3X?
It is a quadratic equation in X.
Is -2x squared plus 2x plus 1 equals 9 a quadratic equation?
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
What is x squared equals 200?
It is a quadratic equation in the one variable.
Is x squared plus 7x-30 equals 0 a linear equation?
No, It's a a quadratic equation because you have X squared.
How many solutions will the equation 25 equals 2x squared 6x have?
The quadratic equation will have two solutions.
What is -2x squared plus 3x plus 5 equals 0?
It is a quadratic equation.
Is 4y squared plus 9 equals - 4 a linear equation?
No. It's a quadratic equation, and it has two solutions.
How do you check whether the equation 7x2x is quadratic?
If it doesn't have an equal sign, then it's an expression, not an equation. The expression 7x2x is quadratic, because it equals 14x², and something is quadratic if it contains the squared exponent ².
