There are no symbols in f(x) nor is there any indication as to where the constant n appears.
However, if you substitute x = 1 and x = 2 into f(x) you will get two equations in m and n. Solve these simultaneously to give you m and n.
To find the third factor, suppose it is (ax + b)
then (x - 1)*(x - 2)*(ax + b) = f(x) = whatever it should be.
so that ax3 + (b-3a)x2 + (2a-3b)x + 2b = f(x)
then compare coefficients of x3 to find a, and the constant term to find b.

What is -5 to the third power?
Raising a number to the third power is the same as multiplying the number with itself, in such a way that there are a total of 3 factors. In this case, (-5) x (-5) x (-5).
Which is a third degree polynomial with -1 and 1 as its only zeros?
You need to multiply three terms, one for each zero. To have only two zeros, the polynomial would need to have a "double zero" (or more generally, a "multiple zero), that is, a repeated factor. In this case, the zeros can be one of the following: -1, -1, 1, with the corresponding factors: (x+1)(x+1)(x-1) or: -1, 1, 1, with the corresponding factors: (x+1)(x-1)(x-1) If you like, you can multiply these factors out to get the polynomial in standard form.
What is the length of the hypotenuse of a right angle triangle when its area is 54 square cm and its perimeter is 36 cm showing how you achieved your answer?
according to the formulae : area of triangle = (1/2) x base of triangle x height 54=(1/2)xBxH B x H = 108 now we have to factorize it.. factors can be.. (12,9),(27,4)(18,6)(36,3) now its given perimeter=36 we have to check two condition for the tringle to be right angle triangle sum of two sides > third side sum of the square of the two sides of triangle(shorter sides)= square of the third side. only one factor (12,9) satisfies both the conditions.. so the third side comes out to be 36-(12+9)=15 so the sides are...12,9,15. that's your answer..

Factor of 9 and 12?
A factor is a number which, when multiplied by another number makes a third number. The factors of 9 are 3 and 3. The factors of 12 are 2, 2 and 3. SO 3 is a common factor of 9 and 12.
What does factoring mean?
Invoice factoring is technically not a loan. a third party, called factor, purchases a business’ invoices at a discount giving the business owner get access to a percent of that invoice now, as opposed to waiting for the invoice or purchase orderto be paid. The balance, minus the set fees are then paid to the business owner once the factor has controlled payment from the business’ customers.

If it has more than two factors. If you find a third factor, you know.
What is the difference between factors and prime factors?
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
