$\huge \bf༆ Answer ༄$

Let's simply ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 5 {x}^{2} (4x - 6 {x}^{2} - 3)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:( - 5x {}^{2} \times 4x) - ( - 5 {x}^{2} \times 6 {x}^{2} ) - ( - 5 {x}^{2} \times 3)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} - ( - 30 {x}^{4} ) - ( - 15 {x}^{2} )$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} + 30 {x}^{4} + 15 {x}^{2}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:30 {x}^{4} - 20 {x}^{3} + 15 {x}^{2}$

Subtract the sum of a^2 − 2ab + b^2 and 2a^2 + 2ab + b^2 from the sum of a^2 − b^2 and a^2 + ab + 3b^2

solniwko [45]

Answer:

-a^2 + ab

Step-by-step explanation:

(a^2 - 2ab +b^2) + (2a^2 + 2ab + b2) = 3a^2 + 2b^2

(a^2 - b^2) + (a^2 + ab + 3b^2) = 2a^2 + 2b^2 + ab

subtract the first part from the second part:

(2a^2 + 2b^2 + ab) - (3a^2 + 2b^2) = -a^2 + ab

If you shift the linear parent function, f(x) = x, up 6 units, what is the equation of the new function?

Annette [7]

To solve this problem you must apply the proccedure shown below:

1. You have the following parent function given in the problem above: $f(x)=x$

2. If you want to shift this parent function up six units, you only have the add a $6$ , then, you will obtain the following new function:

$g(x)=x+6$

Therefore, as you can see, the answer is: $g(x)=x+6$
