The graph in the attached figure
Step-by-step explanation:
we have
This is the equation of a line in slope intercept form
therefore
The slope is positive
The y-intercept is the point (0,7)---> (value of x when the value of y is equal to zero)
The x-intercept is the point (-7,0) ---> (value of y when the value of x is equal to zero)
To graph the line plot the intercepts and join the points
see the attached figure
Firstly expand (x - 3)(ax^2 + bx + c):
ax^3 + bx^2 + cx - 3ax^2 - 3bx - 3c
Now rearrange it so that it's in the form ax^3 + bx^2 + cx + d:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c
Now we can compare both equations:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c = 2x^3 - x^2 - 19x + 12
We get:
(1) a = 2
(2) b - 3a = -1
(3) c - 3b = -19
(4) -3c = 12
If we substitute (1) into (2) we get:
b - 3*2 = -1
b - 6 = -1
b = 5
Now if we solve (4) we get:
-3c = 12
c = -4
Therefor a = 2, b = 5 and c = -4
