What would be the first and last terms of the polynomial if it was rewritten in standard form? answer these quickly without performing all of the indicated operations: (a)- (2x^3 − x^2 − 9x +7) +(11x^2 − 6x^3+ 2x − 9) (b)- (x − 3)(2x +3)(x − 1) (c)- (2x − 3)(3x+ 5) − (x +1)(2x^2 − 6x+ 3)

(a) So first term will be    

(b) So first term will be

(c)  So first term will be

Step-by-step explanation:

We have to find the first and last term of the expression

(a) We have given expression

After addition it will be

So first term will be

(b) We have given equation

After multiplication it will be

So first term will be

(c) We have given expression

It can be written as

So first term will be
