Factor the following expression, and verify that the factored expression is equivalent to the original: 4x^2-9a^6
1 answer:
Answer:
(2x - 3a³) ,(2x + 3a³)
Step-by-step explanation:
Given that
4x^2-9a^6
As we know that
x² - y² = ( x+y)(x-y)
So
4x^2-9a^6 = (2x)² - (3a³)²
By using the above formula
x² - y² = ( x+y)(x-y)
4x^2-9a^6 = (2x)² - (3a³)²
4x^2-9a^6 = (2x - 3a³) (2x + 3a³)
So the factor is (2x - 3a³) ,(2x + 3a³)
To verify
Multiple both factors
(2x - 3a³) (2x + 3a³) = 2x .2x -2x . 3a³ + 3a³ . 2x - 3a³. 3a³
=4x² - 9 a ⁶

B. Y could be inversely varying with X
Answer:
-3/4
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
= (-17- -2)/(24-4)
= (-17+2)/ (24-4)
= -15/20
= -3/4
I don't know how but I got (0,3) and (-0.6,0) don't know if that's right or not.
It is reflecting across the x-axis
