Answer:
- 7x ( 11 x + 12 )
Here first we will multiply 7 with 11
We know
- 7 × 11 = - 77
After multiplying coefficient of x , multiply both the x with each other.
x × x = x²
So
-7x × 11x = - 77x²
Now another term:
Multiplying coefficient of x and constant term first,
- 7 × 12 = - 84
As with 7x is there so multiplying x with - 84 we have -84x
Final :
➺ - 77x² - 84x
