The proof of Theorem3.5is a direct consequence of Theorem3.4. In this case, the monomials will be the terms of the polynomial. Example: 3x2 and -5x2; ½x4 and 2√3x4 The sum of unequal monomials is called a polynomial. 3xy-2 is not, because the exponent is "-2" (exponents can only be 0,1,2,...); 2/(x+2) is not, because dividing by a variable is not allowed 1/x is not either √x is not, because the exponent is "½" (see fractional exponents); But these … 4) Proceed as before. If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and consult the table below. Well, we can also divide polynomials.f(x) ÷ d(x) = q(x) with a remainder of r(x)But it is better to write it as a sum like this: Like in this example using Polynomial Long Division:But you need to know one more thing:Say we divide by a polynomial of degree 1 (such as \"x−3\") the remainder will have degree 0 (in other words a constant, like \"4\").W… Please leave them in comments. Similarly for the third term, we derive with an answer that is -1. The value of (f/g)(x) is determined by dividing the polynomial f(x) by the polynomial g(x) which is only equal to -x2. Tap for more steps... Set up the polynomials to be divided. When a polynomial having degree more than 2 is divided by x-2 the remainder is 1.if it is divided by x-3 then remainder is 3.find the remainder,if it is divided by [x-2][x-3] If 3 and -3 are two zeros of the polynomial p(x)=x⁴+x³-11x²-9x+18, then find the remaining two zeros of the polynomial Get immediate feedback and guidance with step-by-step solutions … Able to display the work process and the detailed step by step explanation. expand polynomial (x-3)(x^3+5x-2) GCD of x^4+2x^3-9x^2+46x-16 with x^4-8x^3+25x^2-46x+16; quotient of x^3-8x^2+17x-6 with x-3; remainder of x^3-2x^2+5x-7 divided by x-3; roots of x^2-3x+2; View more examples » Access instant learning tools.
