What does Reduce increase by a Factor of x means?

divide or multiply the number x times.


In 3x the 3 is called?

While 3 is a number multiplying, it's a coefficient. That has x as is its factor.


Can the graph of a polynomial function have no x-intercept?

Yes, over the real set of numbers. For example, the graph of y=x2+1 is a regular parabola with a vertex that is one unit above the origin. Because the vertex is the lowest point on the graph, and 1>0, there is no way for it to touch the x-axis.NOTE: But if we're considering imaginary numbers, the values "i" and "-i" would be the zeroes. I'm pretty sure that all polynomial functions have a number of zeroes equal to their degree if we include imaginary numbers.


What is the factor of this trinomial x2 plus 13x plus 42?

The easiest way to factor x2 + 13x + 42 is to look at the last number. The last number is 42. Now, think of what whole numbers you can multiply to equal 42. 1 x 42 2 x 21 3 x 14 6 x 7 If you look at the equation, we notice that the sign pattern is + + + When the sign pattern is + + +, we know that whatever two factors you choose must add up to the middle number, 13. So, automatically we can get rid of some of these factors. 1 x 42 --> 1 + 42 doesn't equal 13 2 x 21 --> 2 + 21 doesn't equal 13 3 x 14 --> 3 + 14 doesn't equal 13 Now, we're automatically left with 6 x 7. So, your answer would be (factored out), (x+6)(x+7) Where x = -7, -6

What is a factor in algebra?

A factor is one of two or more numerical or algebraic components of a product. **Note : 1.To factor a counting number means to break it down into its prime number factors. 2.To factor a polynomial is to find its prime polynomial factors, a basic procedure for solving algebraic equations.


What are the factors of the polynomial when you factor with tiles the height and width of the rectangular?

if a is number of tiles high and b is tiles wide then, (x+a) = height and (x+b) = width so the polynomial is (x+a)(x+b).


Where p is a factor of the leading coefficient of the polynomial and q is a factor of the constant term.?

Anywhere. Provided it is not zero, and number p can be the leading coefficient of a polynomial. And any number q can be the constant term.


How do you find greatest common factor of a polynomial equation?

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or polynomials. If you have only one number or polynomial there is nothing for it to have a factor in common with!


Why does any number with a factor of 9 also have 3?

Because 3 is a factor of 9. Any number that has a composite number as a factor will also have that number's factors as factors.


Does any number that has 10 as a factor also have 5 as a factor explain?

Any number that has another number for a factor has that number's factors as factors as well. Since 5 is a factor of 10, all multiples of 10 have 5 as a factor.


How do you know 4 is a factor of a number if eight is a factor?

Because 4 is a factor of 8. Any number that has 8 as a factor will also have 8's factors as factors.
