Question 4 unsaved which of the following is true about the polynomial 6x^2 - x? select all that apply. question 4 options: the polynomial is a binomial. the polynomial is written in standard form. the polynomial has three terms. the polynomial has a leading coefficient of 2.

"Bi" means 2.  There are 2 terms in this polynomial, so the first statement is true.  When a polynomial is written in descending order of exponents, it is in standard form.  Ours starts with an exponent of 2 then goes down to an exponent of 1, so the second statement is true as well.  Our polynomial is a binomial, so that means it has 2 terms, not 3, so the third statement is false.  The leading coefficient is the number that leads the whole polynomial.  Ours is a 6, not a 2.  So the last statement is false as well.  Statements 1 and 2 apply.
