( a + b )^3 = a^3 +b^3 +3 a²b +3b²a + *)
the condition is : r = 1 and p=1
put : x= a and b = 1 in (*) you have :
(x + 1)^3 = x^3 +3x² +3x +1
the zeros is : x = - 1
bcause : x^3 +3x² +3x +1 = 0 (x + 1)^3 = 0 so : x = - 1
answer: (x,> (4x,4y)
1. by definition, dilation is as a transformation in which the figure is enlarged or reduced.
2. for dilation you have:
- a scale factor, that determines how much the figure will be reduced or enlarged.
- the center of dilation, which is defined a a fixed point in the plane.
3. if the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply each coordinate of the original figure by 4, then. then, the rule is:
