Expert Answer

Step 1

We need to factor t...

x4 7x2 30
t x2
Let,
x47x2 30 = t2 - 7t - 30
so,
= t2 - 10t +3t - 30
- t(t 10)3(t - 10)
= (t 3) (t - 10)
(x23)x2 10)
[as t x2]
=

x4 7x2 30 t x2 Let, x47x2 30 = t2 - 7t - 30 so, = t2 - 10t +3t - 30 - t(t 10)3(t - 10) = (t 3) (t - 10) (x23)x2 10) [as t x2] =
