1000 views=£2<br> how many views are required to make £31?
dedylja [7]
1000 = £2
10 x 1000 = 10,000 = £20
15,000 = £30
16,000 = £32
Not sure if you want specifically 31 but I’d say if you do it would be 15,000 views

Brainliest 5 stars Thanks!<br> Use the Remainder Theorem.
GalinKa [24]

Answer:

If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.  

actually this factors by grouping:

f(x)=x³+3x²-x-3

= x²(x+3)-1(x+3)

=(x+3)(x²-1)

=(x+3)(x-1)(x+1) // difference of squares

By zero product property roots are

-3, -1, 1
