Here we are given the expression:
Now let us equate it to zero to find x first,
Now subtracting 18 from the other side,
taking square root on both sides,
So we will get two values of x as ,
Now we can write square root -1 as i,
So our factors become,
Answer:
The final factored form becomes,
xy - -4x²
Step-by-step explanation:
(2x - 3y)(4x -y)
2x( 4x -y) -3x( 4x - y)
8x² - 2xy - 12x² + 3xy
8x²- 12x²- 2xy + 3xy
-4x² + xy
xy - -4x²
