Answer:
Step-by-step explanation:
12x³ = 2²·3·x³
The greatest common factor of 12x³ and 3x² is 3x².
12x³ - 3x² = (4x - 1)3x²
ANSWER

EXPLANATION
The sum of the interior angles of a triangle is 180°
We can rewrite this as:

The sum of interior angles of a quadrilateral is 360°
We can also rewrite this as:
In general an n-sided polygon has
the sum of the interior angles given by the formula:

Its A trapezium
For Calculations Refer to the attachment
OK well take out the 6 for the first form
= 6(2x^2 + x + 4)
Also we can factor the first 2 terms to give the second form:-
= 6x(2x + 1) + 24
