2. 2x³ + 7x² -8 is a
i) monomial
ii) Binomial
iii) Trinomial
iv) Zero

3.whic of the following is not a polynomial
i) 1/(x + 1)
ii) 7
iii) x² - 3
iv x²- 4x + 5

4. The factor of 3x² - x - 2 is
i) x-1
ii) 3x -2
iii) 3x+2
iv) 2x-2​

Answer 1

Answer:

-17/4 by putting 2x-1=0 and x=-1/2 in equation

Step-by-step explanation:

2. trinomial as it has three terms

3. 7 as it is a constant

4. now to take factor remainder should be zero and so to do that we find roots by bhramgupta quadratic formula which give us x=1,-2/3and so factor take opposite sign which will give us (x-1)(x+2/3) so to option here it is x-1
