Question

Write the constant term of
(i) 3x² + 5x + 8
(ii) 2x² − 9
(iii) $4y^2-5y+\frac{3}{5}$
(iv) $z^3-2z^2+z-\frac{8}{3}$

Answer 1

A term of expression having no literal factors is called a constant term.
(i) In the expression 3x² + 5x + 8, the constant term is 8.
(ii) In the expression 2x² − 9, the constant term is -9.
(iii) In the expression ${\mathrm{4y}}^2-5y+\frac{3}{5}$, the constant term is $\frac{3}{5}$.
(iv) In the expression $z^3{-2z}^2+z-\frac{8}{3}$ , the constant term is $-\frac{8}{3}$.
