Answer:
-(x + 6)(x - 7)
Step-by-step explanation:
The expression that we have can also be expressed in the following way:
- (x ^ 2 - x - 42)
Now to factorize we must find two numbers that multiplied by -42 and the sum of these numbers by -1.
these numbers are: -7 and 6
-7 * 6 = -42
-7 + 6 = -1
Thus:
- (x + 6) (x - 7)
roots (1,0) (3,) the vertical intercept is (0,-12)
x=6 y=-3 (6,-3)
Step-by-step explanation
a=4 and b=-1
2(4)+3(-1)= 5
