Use the discriminant to determine how many real number solutions the quadratic equation -4j to the second power plus 3j - 28 equals 0 has?
It has no real roots.
Discriminant of 7x to second power minus x plus 1 equals 0?
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.
Is x3-27 equals 0 a quadratic equation?
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.
-20xto power of 2 plus 10x plus 10 equals 0 what is the value of discriminant?
The discriminant is 900.
What is X to the power of 2 minus 8 X plus 15 equals 0?
It is a quadratic equation and its solutions are: x = 3 and x = 5
Use the discriminant to determine how many real number solutions the quadratic equation -4j to the second power plus 3j - 28 equals 0 has?
It has no real roots.
Is 3x4 plus 2x plus 5 equals 0 a quadratic equation?
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
Is 4x plus 5c plus 10c-3x equals 0a quadratic equation?
NO,because in quadratic equation highest power of a variable is 2. e.x. 4x2-20x+10=0.
Discriminant of 7x to second power minus x plus 1 equals 0?

How do you know if a equation is a quadratic one?
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.
Its y equals 4x3 plus 4x2 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.
Is x2-27 equals 0 a quadratic 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)
-20xto power of 2 plus 10x plus 10 equals 0 what is the value of discriminant?
The discriminant is 900.
How many roots does a quadratic equation in one variable have?
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.
What is the name for a polynomial equation containing a variable to the second power?
A quadratic equation.
What is x to the 2nd power minus 9x plus 90?
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
