6x²-5x+4 - 6x³+7x²-5x+3

-6x³ +13x² -10x +7

Answer 2

Step-by-step explanation:

$\huge{ \color{red}{ \boxed{ \color{blue}{hello}}}}$

Your question:

$(4 - 5 x+ 6 {x}^{2} - 8 {x}^{3} ) - (6 {x}^{3} - 7 {x}^{2} + 5x - 3)$

Your answer:

$= 4 - 5x + 6 {x}^{2} - 8 {x}^{3} - 6 {x}^{3} + 7 {x}^{2} - 5x + 3$

[ open the brackets but be careful with the second bracket expression as negative and positive or negative and negative will get multiplied and will result as given above ]

$= (4 + 3) + ( - 5x - 5x) + (6 {x}^{2} + 7 {x}^{2} ) - ( {8x}^{3} - 6 {x}^{3} )$

[ put the like terms inside the bracket ]

$= 7 - 10x + 13 {x}^{2} - 2 {x}^{3}$

[ do the mathematical functions ]

Your final answer:

$\huge{ \color{red}{ { \color{lime}{ = 7 - 10x + 13 {x}^{2} - 2 {x}^{3} }}}}$
