How many roots does the polynomial function, y = (x-8)(x+3)2 have?

SUBMIT

(x−8)(x+3)(2)

=2x2−10x−48

Step-by-step explanation:

If we count roots according to their multiplicity (see The Factor Theorem), then: A polynomial of degree n can have only an even number fewer than n real roots. Thus, when we count multiplicity, a cubic polynomial can have only three roots or one root; a quadratic polynomial can have only two roots or zero roots.

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
