2 answers:
Answer:
Step-by-step explanation:
We are given the expression
and asked to evaluate when x=3 and y=1. Therefore, we must substitute 3 in for x and 1 in for y.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Multiply 2 and 3.
Add 1 and 6.
The expression 2x+y evaluated at x=3 and y=1 is equal to 7.

In plain text, it is appropriate to express the division using a division bar (/) and parentheses around the numerator and denominator:
(3x^4 +7x^3 +2x^2 +13x +5)/(x^2 +3x +1)
It is best to reserve the square root symbol (√) for an actual square root.
Your quotient is
3x^2 -2x +5
(3x^4 +7x^3 +2x^2 +13x +5)/(x^2 +3x +1)
