Question

factorise 3/5 x^2 - 19/5x + 4

Answer 1

Answer:  [3x - 4][x-5]

Step-by-step explanation:

$\frac{3}{5} x^{2} - \frac{19}{5} x + 4 = 0 \\3x^{2} - 19x + 20 = 0 \\3x^{2} - 15x - 4x +20 = 0$

3x[x-5] - 4[x-5] = 0

(x-5)(3x- 4) = 0

Answer 2

Answer:

⅗x² - 19/5x +4

= ⅕ (3x² - 19x + 4×5 )

= ⅕ ( 3x² - 19x +20 )

= ⅕ [ 3x (x - 5) - 4 ( x - 5 ) ]

= ⅕ ( 3x-4 ) ( 4-5 )

= ⅕ ( 3x-4 ) ( ⅘ - 1 ) :- Answer
