I’m pretty sure yes it is
Answer:
66a
Step-by-step explanation:
Hello there,
The equation that we have to factor is as follows:
2x² + 3x - 54
In order to factor this we first multiply (-54) by 2 and try to find two factor pairs that can be add up to 3.
For this we would use 12 * -9 which gives you -108 when multiplied and when added you would get 3.
2x² + 12x - 9x -54
2x(x + 6) -9(x +6)
(2x - 9) (x + 6)
Now the factor pairs would be: (2x - 9)(x + 6)
Hope I helped,

a) After 4 years the profit will change from negative to positive.
b)after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) after 4 years the profit will be 5.
<u>Step-by-step explanation:</u>
a) After 1 year = 2(1) -6(1) -3
= 2-9
= -7
It's negative
After 2 years = 2(4) -6(2) -3
= 8-12-3
= -7
It's negative
After 3 years = 2(9) -6(3) -3
= 18 - 18 -3
= -3
It's negative
After 4 years = 2(16) -6(4) -3
= 32 -24-3
= 5
It's positive
After 4 years the profit will change from negative to positive
b) after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) profit = 2(16) - 6(4) -3
= 32 -24 - 3
= 5
after 4 years the profit will be 5
