Let p (x) = 5x^3+8x^2-7x-6

using factor theorem,
(x+2) is a factor of p (x) only if p (-2) = 0

p (-2) = 5×-2^3+8×-2^2-7×-2-6
= -40+32+14-6
= -40 + 40
= 0
since remainder = 0
therefore (x+2) is a factor of p (x)

Again,
using factor theorem,
(x+1) is a factor of p (x) only if p (-1) = 0

p (-1) = 5×-1^3+8×-1^2-7×-1-6
= -5 + 8 + 7 - 6
= 3 + 1
= 4
since remainder is not equal to 0
therefore (x+1) is not a factor of p (x)

HELP any1 good at math?
valentina_108 [34]

Step-by-step explanation:

the equations are :-

=》d = 40m + 200

=》d = 50m

here, by equalising both equations.

( since, d = d )

=》40m + 200 = 50m

=》50m - 40m = 200

=》10m = 200

=》m = 200 ÷ 10

=》m = 20

now,

=》d = 50m

=》d = 50 × 20

=》d = 1000

The sum of two numbers is 48.when the smaller number is subtracted from the larger number,the difference is 12. What are the two
Savatey [412]

Answer:

The two numbers are:

30 and 18

Step-by-step explanation:

a + b = 48

a - b = 12

From the first eq.

a = 48 - b

Replacing this last value in the second eq.

(48 - b) - b = 12

48 - 2b = 12

48 - 12 = 2b

36 = 2b

36/2 = b

18 = b

from the first eq.

a + 18 = 48

a = 48 - 18

a = 30

Check:

from the second eq.

a - b = 12

30 - 18 = 12
