Answer 1

Answer:

3) $x^{2} +5x-36$

⇒$x^{2} +4x-9x-36$

⇒$x(x+4)-9(x+4)$

⇒$(x+4)(x-9)$

4)$2t^{2} -t-10$

⇒$2t^{2} -5t+4t-10$

⇒$t(2t-5)+2(2t-5)$

⇒$(t+2)(2t+5)$

Hope it helps, please mark me as brainliest, thanks! :)

Answer 2

Answer:

hope it helps .....mark me as brainleast.

Step-by-step explanation:

1. x²+5x-36

=x²-4x+9x-36

=x(x-4)+9(x-4)

=(x-4)(x+9)

2. 2t²-t-10

=2t²+4t-5t-10

=2t(t+2)-5(t+2)

=(t+2)(2t-5)
