Question

factorise 3u^2-10u+3​

Answer 1

Step-by-step explanation:

$3 {u}^{2} - 10u + 3 \\ 3 {u}^{2} - 9u - u + 3 \\ 3u(u - 3) - 1(u - 3) \\ (3u - 1)(u - 3) \\ u - 3 = 0 \\ u = 3 \\ \\ 3u - 1 = 0 \\ \frac{1}{3} = u$

Answer 2

Answer:

(3u-1)(u-3)

Step-by-step explanation:

3u^2-10u+3

3u^2-9u-u+3

3u(u-3)-1(u-3)

(3u-1)(u-3)
