Ex 2.1, 1 Which of the following expressions are polynomials in one variable and which are not? State reasons for your answer. (i) 4𝑥2 – 3𝑥 + 7 4𝑥2 – 3𝑥 + 7 = 4𝑥2 – 3𝑥1 + 7 𝑥0 Here power of equation is 2,1 and 0. Since all powers are whole number, it is a polynomial Now since there is only one variable x, it is polynomial in one variable Yes, this expression is a polynomial in one variable x.
