What will be the constant term in ((4x-3)^2)?

Answer and explanation

Correct answer: 9

Using the identity
\((a-b)^2=a^2-2ab+b^2\), we get
\((4x-3)^2=16x^2-24x+9\). The term without x is the constant term, so it is 9. Here, -24 is the coefficient of x, while 16 is the coefficient of \(x^2\). Exam tip: in the square of a binomial, the square of the numerical term gives the constant term.
