Write the coefficients of x^2 in each of the following
(i) 2 + x^2 + x
(ii) 2 - x^2 + x^3
(iii) pi/2x^2 + x
(iv) √(2)x - 1
A coefficient is a number or quantity that is associated with a variable. It's commonly an integer multiplied by the variable immediately adjacent to it.
The x2 coefficient is 1.
The x2 coefficient is -1.
The x2 coefficient is π /2.
In the provided formulation, there is no x2 term. It can be rewritten as 0x2 +√ 2x - 1
The coefficient of x2 equals 0 because x2 does not exist.
(i) 2+x2+x , the coefficient of x2 is 1.
(ii) 2-x2+x3, the coefficient of x2 is -1.
(iii) (π/2)x2+x, here the coefficient of x2 is π/2.
(iv) √2x-1, the coefficient of x2 is 0.
