Answer:
(6a - 7b)(6a + 7b)
Step-by-step explanation:
Given
36a² - 49b² ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
36a² - 49b²
= (6a)² - (7b)²
= (6a - 7b)(6a + 7b)
If it is ....
The coefficient of x² is (( 3 ))
& the coefficient of x is (( -2 ))
_________________________________
If it is .....
The coefficient of x² is (( zero 0 ))
& the coefficient of x is (( 1 ))
Cool. I hope she knows how to do it. (ahem)
The vertex is (12,-9). Hope this helps.
