Write the coefficient of x2 in each of the following: (i) 17 – 2x +

1.	Write the coefficient of x2 in each of the following: (i) 17 – 2x + 7x2 (ii) 9 – 12x + x3 (iii) \(\frac{\pi}{6} x^2 - 3x + 4\)(iv) √3x – 7
Answer» (i) 17 – 2x + 7x² Coefficient of x² = 7 (ii) 9 – 12x + x³ Coefficient of x² =0 (iii) \(\frac{\pi}{6} x^2 - 3x + 4\) Coefficient of x² = \(\frac{\pi}{6}\) (iv) √3x – 7 Coefficient of x² = 0

Write the coefficient of x2 in each of the following: (i) 17 – 2x + 7x2 (ii) 9 – 12x + x3 (iii) \(\frac{\pi}{6} x^2 - 3x + 4\)(iv) √3x – 7

Answer»

(i) 17 – 2x + 7x²

Coefficient of x² = 7

(ii) 9 – 12x + x³

Coefficient of x² =0

(iii) \(\frac{\pi}{6} x^2 - 3x + 4\)

Coefficient of x² = \(\frac{\pi}{6}\)

(iv) √3x – 7

Coefficient of x² = 0
