Question

Can someone solve these for me? its factoring trinomials

you can dm the answers on ig as well if you'd like

Answer 1

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)`
