It is B, 0.
It has no real roots.
The discriminant in the quadratic equation is the term B2-4AC. This is the part under the square root sign, with the full form being (-B +/- SquareRoot (B2-4AC)) / 2A. If the original poloynomial is 7x2 - x + 1 = 0, then A=7, B=-1, and C=1, so the discriminant is -27. Since this is negative, there are two complex conjugate roots.
No, it's a cubic equation. A quadratic equation contains, as its term raised to the highest power, a square. Example: x2. A cubic equation contains, as its term raised to the highest power, a cube. Example: x3. A quartic equation contains, as its term raised to the highest power, a term raised to the fourth power. Example: x4. Quintic, x5. And so, on.
The discriminant is 900.
It is a quadratic equation and its solutions are: x = 3 and x = 5
It has no real roots.
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
NO,because in quadratic equation highest power of a variable is 2. e.x. 4x2-20x+10=0.

You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
Interpreting this equation as y=4x3+4x2 This is not a quadratic equation. By definition, a quadratic equation is a polynomial equation of order two, meaning it is composed only of coefficients multiplied by x's raised to any exponential power of maximum 2. The most that any of the exponents in the equation can be is 2. Since this equation has a term of 4x3, it is not quadratic since this term has an exponent of 3. This means that the equation is of degree three. This equation is a cubic equation.
Yes. Since 'x' appears to the 2nd power, the equation is "second degree", or 'quadratic'.Also, since 'x' appears to the 2nd power, there are two solutions.x = +3 sqrt(3)x = -3 sqrt(3)
The discriminant is 900.
A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.
A quadratic equation.
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
