Answer:
Step-by-step explanation:
(a). 270° clockwise or 90° counterclockwise:
(x, y) --------> ( - y, x )
(b). 270° counterclockwise or 90° clockwise:
(x, y) ---------> ( y, - x )
Answer:
a = 1
b = -1
c = -2
Step-by-step explanation:
We reorder the equation in such way that let us see the usual
ax² + bx + c = 0
Then the original quation is:
-2 = - x + x² - 4 ⇒ 0 = 2 - x + x² - 4 ⇒ x² - x - 2 = 0
Now we are able by simply inspection to identify a, b . c comparing our equation with the general equation so :
a = 1
b = -1
c = -2
