Answer:
p(x) = x^12 -19x +84
Step-by-step explanation:
Adding the given equations yields ...
2·alpha = 19+5
alpha = 24/2 = 12
Then beta = 19-12 = 7
The factored form of p(x) is then ...
p(x) = (x -12)(x -7)
Multiplying this out gives ...
p(x) = x^2 -19x +84
_____
Another way to get there is to realize that ...
p(x) = x^2 -(alpha+beta)x +(alpha·beta)
The constant term can be computed from the given sum and difference as ...
alpha·beta = ((alpha+beta)^2 -(alpha-beta)^2)/4 = (19^2 -5^2)/4 = 84
Then ...
p(x) = x^2 -19x +84
Answer:
D 3/4 × 3/4
Step-by-step explanation:
The part of the circle that is black is 1/4 of the circle. The remaining 3/4 is divided by the dashed lines into 4 equal parts, so each of those parts is 1/4 of 3/4 of the circle. 3 of the parts are shaded blue, so those represent ...
... 3/4 × 3/4 . . . of the circle
