Coefficient of x in (x + 9)(8 - 5x) is
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Eg : In $$ax^2$$, coefficient is $$a$$
Expression : $$(x + 9)(8 - 5x)$$
= $$8x - 5x^2 + 72 - 45x$$
= $$-5x^2 - 37x + 72$$
$$\therefore$$ Coefficient of $$x$$ = -37
