Hi, can someone help with these two questions ASAP! (Ignore the multiple choice I circled, not sure if it’s correct) Thanks!!

1) D.

2) E. The coefficient of is -16.

Step-by-step explanation:

1) A polynomial is an algebraic expression of the form , where is the grade of the polynomial. In this case, the only equation that satisfies this definition is:

Correct D

2) Let , we proceed to expand the expression by algebraic means:

We see that coefficients for and are -16 and 0, respectively. Hence, the incorrect answer is E.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
