Question

Write the co-efficient of x² in each of the following.

i) 15 – 3x + 2x²

ii) 1 -x² 

iii) πx² – 3x + 5 

iv) √2x² + 5x – 1 

Answer 1

Write the co-efficient of x² in each of the following.

i) 15 – 3x + 2x² : co-efficient of x² is 2 

ii) 1 -x² : co-efficient of x² is -1 

iii) πx² – 3x + 5 : co-efficient of x² is π 

iv) √2x² + 5x – 1 : co-efficient of x² is √2
