Write the coefficient of x^2 and x in each of the following polynomials, (i) 4 + (2/5)x^2 - 3x (ii) 6 – 2x^2 + 3x^3 - √7x (iii) πx^2 – x + 2

Question

Write the coefficient of x² and x in each of the following polynomials,

(i) 4 + \(\frac{2}{5}x^2\) - 3x

(ii) 6 – 2x² + 3x³ - √7x

(iii) πx² – x + 2

(iv) √3x² + √2x + 0.5

(v) x² - \(\frac{7}{2}x\) + 8

Answer 1

	Polynomial	Co-efficient of x2	Co-efficient of x
(i)	4 + \(\frac{2}{5}x^2\) - 3x	\(\frac{2}{5}\)	-3
(ii)	6 – 2x2 + 3x3 - √7x	-2	-√7
(iii)	πx2 – x + 2	π	-1
(iv)	√3x2 + √2x + 0.5	√3	√2
(v)	x2 - \(\frac{7}{2}x\) + 8	1	\(-\frac{7}{2}\)
