Pascal Triangle and Binomial Expansion- Math APP 2- WRITTEN

Find the sum of the given algebraic expressions

Write numeric answer only

(a)  

Find the value of a and b that would make the statement true:   $4\left(ax^2-5x+3\right)=8x^2+bx+12$  

Select all that applies.

Find the coefficient of $x^2$  in the expansion of the following:
 $\left(2x^2+5x-7\right)\left(x^2-6x+4\right)$  

True of False: The expansion of 

 $\left(2t+\frac{3}{t}\right)^4=16t^4+96t^2+216+216t^{-2}+81t^{-4}$  

The term  $yx^2$ will appear in this version of the Pascal triangle. Name this row

A given expansion gives a partial solution as shown below: $1\left(3a\right)^5+5\left(3a\right)^4\left(-2b\right)+10\left(3a\right)^3\left(-2b\right)^2+5\left(3a\right)\left(-2b\right)^4+1\left(-2b\right)^5$  The expansion that would result in the solution shown above is
