Question

Write the coefficient of x² in each of the following:

(i) 17 – 2x + 7x²

⁽ⁱⁱ⁾ 9 - 12x + x³

^{(iii) \(\cfrac{\pi}{6}\)} x² – 3x + 4

(iv) \(\sqrt{3}\) x - 7

Answer 1

Coefficient of x² in:

(i) 17 – 2x + 7x² is 7

(ii) 9 - 12x + x³ is 0

(iii) \(\frac{\pi}{6}\) x² – 3x + 4 is \(\frac{\pi}{6}\)

(iv) \(\sqrt{3}\) x - 7 is
