Answer:
x = - 7 , x = 2 , x = 1
Step-by-step explanation:
note that
p(1) = 1³ + 4(1)² - 19(1) + 14 = 1 + 4 - 19 + 14 = 0
since p(1) = 0 , then x = 1 is a zero
using synthetic division
1 | 1 4 - 19 14
↓ 1 5 - 14
------------------------
1 5 - 14 0
quotient is x² + 5x - 14
equating quotient to zero
x² + 5x - 14 = 0
(x + 7)(x - 2) = 0
equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
then zeros are x = - 7, x = 2 , x = 1

62 rows of 9 chairs.
The questions asks about how many, so we are estimating. So we will round 62 down to 60 and 9 up to 10.
So, 60 rows of 10 chairs.
Then we multiply 60 * 10 to get 600.
The exact amount of 62*9 = 558, but we are estimated so our estimation would be there are about 600 chairs.
