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

How do you find x in 8 equals -16x2 plus 30x plus 3.5?

ANYTIME. a number is next to a variable it means that number has to be multiplied by the variable. Try writing it out as 30 times x in the equation. Its quite simple just refere to the Order of operations and PEMDAS search around if you are not sure on how to find the value of a variable. Its actually quite simple. Since I infer you are probably doing homework I don't want to go ahead and give you the value so this is the most i can help you.
