Question

f(x) = 0.3x^4 − 2.7x^3 + 1.5x^2 + 5 use synthetic division to find f(1) can someone teach me how to solve this?

Answer 1

They've given you f(1), that means that (x-1) is a factor of the whole equation

Answer 2

So you take (x-1) divide 0.3x^4 − 2.7x^3 + 1.5x^2 + 5

Answer 3

So you do the synthetic division,

Answer 4

The remainder is 4.1

Answer 5

So,
f(x) = 0.3x^4 − 2.7x^3 + 1.5x^2 + 5
f(1) = 4.1

Answer 6

ooh thank you so much
