Question

1. Which of the following expressions are polynomials in one variable and whick. I
not? State reasons for your answer.
() 4x2-3x+7
(i) y2 + 2
(i) 3Vi +
(iv) y +
(v) x + y + po​

Answer 1

Answer:

1,2,4

Step-by-step explanation:

1] 4x2-3x+7 is a polynomial in one variable because this number has only one variable that is X

2] y2+2 is a polynomial in one variable because this number contains only one variable that os Y

3] 3Vi+ it is not a polynomial in one variable because it has two variable that is V and i

4] y+ it is a polynomial in one variable because of Y Only

5] x+y+po it is not a polynomial in one variable because it contain three variable that is x,y and po

Answer 2

The equation 4x²–3x+7 can be written as 4x²–3x1+7x0

Since x is the only variable in the given equation and the powers of x (i.e., 2, 1 and 0) are whole numbers, we can say that the expression 4x²–3x+7 is a polynomial in one variable.
