Question

which binomial is a factor of 4x^2-13x+3?
A. 2x-3
B. 2x-1
C. 4x-3
D. 4x-1

Answer 1

Best to just factorise. However, you could use the factor theorem if you really don't feel like it:

If f(a) = 0, than (x-a) is a factor. Note , for example, 2x -1 = 2(x - (1/2))

Answer 2

?

Answer 3

you just confused me lol

Answer 4

:(

Answer 5

is it d?

Answer 6

Yes.

Answer 7

o ok. you didnt confuse me so much

Answer 8

thanx

Answer 9

Note if you let x = (1/4)

\[f(x) = 4 \times \frac{1}{4}^2-13 \times \frac{1}{4} + 3 = 0 \]

Answer 10

Factors into (4x - 1)(x - 3) = 0
