=2(35m +25m)

= 2(60m)

Alik [6]

$k(x) - g(x) + f(x)$

$(k(x) + f(x)) - g(x)$

$((2x + 5) + (x - 1)) - ( {6x}^{2} - 4x + {3x}^{4}$

$(2x + 5 +x - 1) - 6 {x}^{2} + 4x - {3x}^{4}$

$2x + 5 +x - 1 - 6 {x}^{2} + 4x - {3x}^{4}$

$( - {3x}^{4} ) + ( - {6x}^{2} ) + (2x + x + 4x) + (5 - 1)$

$- {3x}^{4} - {6x}^{2} + 7x + 4$
