Factor the expression: 7x(x^2-1)-3(x^2-1)

x = 1

Step-by-step explanation:

The factors of the given expression is as follows:

If we considered x = 1

So

7 - 3 -7 + 3 = 0

0 = 0

Hence, the factor would be x = 1

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
