Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

81 {x}^{2}  - 324 {y}^{2}  \\  \\  =  {(9x)}^{2}  -  {(18y)}^{2}  \\  \\  = (9x + 18y)(9x - 18y) \\  \\  = 9(x + 2y) \times 9(x - 2y) \\  \\  = 81(x + 2y)(x - 2y)

Calculate the vertex of the parabola using the equation <br> Please helppp meee :((
koban [17]

FACTOR ALL OF THE EQUATIONS INTO "y = (x-h)^2 + k," AND THE EQUATION'S VERTEX IS (h,k)

10. y = (x+2)^2 - 11 --> (-2, -11)

11. y = -(x-4)^2 + 32 --> (4, 32)

12. y = 3(x-1)^2 - 5 --> (1, -5)

13. y = -2(x+2)^2 + 5 --> (-2, 5)

14. y = 2(x+1)^2 - 1 --> (-1, -1)

15. y = -5(x-1)^2 + 8 --> (1, 8)

16. y = 3(x-3)^2 - 26 --> (3, -26)

17. y = (x+5)^2 - 32 --> (-5, -32)

18. y = -(x-3)^2 + 10 --> (3, -10)

Describe the roots of the polynomial function shown below.
Allisa [31]

Answer:

Graphically. As shown below, the roots of a polynomial are the values of x that make the polynomial zero, so they are where the graph crosses the x-axis, since this is where the y value (the result of the polynomial) is zero. The roots are the two green dots.
