Answer:

\boxed{\sf 15x^2 + 2}

Step-by-step explanation:

Simplify the expression:

\sf \implies(10 {x}^{2}  - 1 + 4x) + (3 + 5 {x}^{2}   - 4x)

Grouping like terms, 10x² + 5x² + 4 x - 4 x - 1 + 3 = (10 x² + 5x²) + (4 x - 4 x) + (-1 + 3):

\sf \implies (10 x^2 + 5 x^2) + (4 x - 4 x) + (-1 + 3)

10x² + 5x² = 15x²:

\sf \implies 15 x^2 + (4 x - 4 x) + (-1 + 3)

3 - 1 = 2:

\sf \implies 15 x^2 + (4 x - 4 x) + 2

4 x - 4 x = 0:

\sf \implies 15 x^2 + 2

The coordinates of the point P are (6,0)

We need to determine the coordinates of the point P'

Coordinates of the point P':

The coordinates of the point P' can be determined by substituting the coordinates of the point P(6,0) in the translation.

Thus, substituting the coordinates, we have;

Simplifying the coordinates, we get;

Thus, the coordinates of the point P' is (0,-1)
