Answer:

1.)
\left(x-3\right)\left(x+6\right)

2.)
\left(a-3\right)^2

3.)
=\left(t+8\right)\left(t-9\right)

4.)
=\left(b+7\right)^2

Explanation:

2.)
=a^2-2a\cdot \:3+3^2,
\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a-b\right)^2=a^2-2ab+b^2.


a=a,\:b=3


=\left(a-3\right)^2

3.)
=\left(t^2+8t\right)+\left(-9t-72\right)
=t\left(t+8\right)-9\left(t+8\right),
\mathrm{Factor\:out\:common\:term\:}t+8.


=\left(t+8\right)\left(t-9\right)
