Factorising, we have,

9x2+ 30x + 25 = (3x + 5)2;thus,

when y = 0, x = -1⅔.

This tells us that the sole x-intercept of this function is at the vertex, (0, 1⅔).

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
