The answer is: " -12x³ + 28x² " .

Note the "distributive property of multiplication" :
___________________________________________a(b+c) = ab + ac ;a(b−c) = ab − ac ;___________________________________________
So; given: " - 4x² (3x - 7) " ;
→ - 4x² (3x <span>−</span> 7) ;
= [ -4x² * 3x ] − [- 4x² * -7 ] ;
= -12x³ − (28x²) ;
= -12x³ − 28x² .

First, we want to subtract the numbers within the parenthesis. However, to do this we must put each number over a common denominator. We can do his by multiplying
6
by the appropriate for of
1
:
2
3
(
6
−
5
6
)
⇒
2
3
(
[
6
6
×
6
]
−
5
6
)
⇒
2
3
(
36
6
−
5
6
)
⇒
2
3
(
31
6
)
Next, we can multiply the two fractions to complete the evaluation of the expression:
2
3
(
31
6
)
⇒
2
3
×
31
6
⇒
2
×
31
3
×
6
⇒
62
18
Now, we can factor the numerator and denominator so we can cancel common terms. This will give the simplest form of the fraction:
2
×
31
2
×
9
⇒
2
×
31
2
×
9
⇒
31

Step-by-step explanation:
An input can only have 1 output, but multiple inputs can have the same output. How you can check this if you have a graph is if you can draw a straight line (top to bottom) anywhere on the graph and it intersects with the line once or not at all.
