A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How many solutions to a quadratic equation?

2


How can you tell when an equation in one variable has infinitely many solutions or no solutions?

There is no simple method. The answer depends partly on the variable's domain. For example, 2x = 3 has no solution is x must be an integer, or y^2 = -9 has no solution if y must be a real number but if it can be a complex number, it has 2 solutions.


How many solutions does the equation have?

how many solutions does the equation have? 4x+1=5+2(2-4) a. one solution b. infinite solutions c. no solution


How many solutions does an equation have when tthe variable adds out and the final sentence is false?

2(2x-1)+2x=6(x-1)


If the discriminant is positive how many solutions does the equation have?

If an equation has a degree of three how many solutions will there be?

If the highest degree of an equation is 3, then the equation must have 3 solutions. Solutions can be: 1) 3 real solutions 2) one real and two imaginary solutions.


How many total solutions are there to any quadratic equation?

In general how many distinct solutions are there to a quadratic equation?

the maximum number of solutions to a quadratic equation is 2. However, usually there is only 1.


What is an equation that is not true for any value of the variable?

It is an equation with no solutions [in the given domain]. There may (or may not) be solutions if you change the domain.For example, if X is an integer, then 5X = 2 has no solution. But if you change the domain to rational numbers, then X = 2/5 or 0.4 is a solution.


If the discriminant is zero the equation has solutions?

It has 2 equal solutions


Is it possible for an equation to have many solutions and can an equation have no solutions?

Yes and yes. eg x = y + 1 has an infinite number of solutions, and {sin(x) + cos(x) = 2} does not have a solution.


When you square each side of an equation is the resulting equation equivalent to the original?

No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2No. The resulting equation has more solutions. For example, x = 2 has only one solution and that is x = 2.butx2= 4, the squared equation, has two solutions: x = +2 and x = -2
