1. QUOTIENT AND REMAINDER FOR THE SUM 115/7
Appropriate evaluation of the sum 115/7 indicates that its quotient and reminder 16 R4.
2. IS (X+2) A FACTOR OF THE POLYNOMIAL X^3-3X^2-4X+12
As per the detailed analysis of polynomial, (x+2) is a factor of polynomial x^3-3x^2-
4x+12. It helps in analysing the final outcome of polynomial.
3. HIGHER ORDER FOR WRITING OUT 4X^2-5X+3X^3-5+5X^4
POLYNOMIAL
5-5x+4x^2-3x^3+5x^4 is considered as a higher order for the writing out 4x^2-5x+3x^3-
5+5x^4 polynomial. Professionals need to ensure about such values in desired manner.
4. ANSWER OF POLYNOMIAL LONG DIVISION, 12X^3-11X^2+9X+12
WHEN IT IS DIVIDED BY 4X+3
According to proper evaluation, it can be state that 3x^2-5x+6 is considered as correct
answer to the polynomial long division, 12x^3-11x^2+9x+12 when it is divided by 4x+3
5. IS IT TRUE OR FALSE THAT SYNTHETIC DIVISION CAN ALWAYS
BE USED WHEN DIVIDING POLYNOMIALS
It is true that synthetic division can always be used when dividing polynomials
6. WHAT ARE THE PARTIAL FRACTIONS OF [X/X-2] + [3/X+1]
Partial fraction for the [x/x-2] + [3/x+1] can be classified as 5x-4/x^2-x-2
7. BEFORE A FRACTIONAL FUNCTION CAN BE EXPRESSED
DIRECTLY IN PARTIAL FRACTIONS
It has been noticed that before a fractional function can be expressed directly in partial
fractions, when the numerator must be greater than the denominator. It allows to attain the
appropriate expression in regard to the services.
8. IS THE EXPRESSION 5X/[(X^2+X+1)(X-2)]
5x/[(x^2+x+1)(x-2)] is referred as quadratic partial fraction
