Answer:
P(x) =
- 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x =
, x = - 
Then the factors are (x - 2), (x + 2), (x -
), (x +
)
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x -
)(x +
) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
=
- 3x² - 4x² + 12 ← collect like terms
=
- 7x² + 12
Answer:
I think its D
Step-by-step explanation:
It is between A&D but it just depends on if it says equal to or not and if not then it's D
1: base
2: acute angle
3: dimensions
4: height
5: obtuse angle
6: area
7: square units
the answer is B your welcome
Use the following identity:
cos(2x)=1-2sin^2(x)
