Step-by-step explanation:
Hey, there!!
While simplifying the algebraic expression, you must be very careful about the signs.
Here,
(6x-4) (9x-2)
Multiply 2nd expression by 1st expression,
= 6x ( 9x - 2) -4 ( 9x - 2)
[tex] = (54 {x}^{2} - 12x) - (36x - 8)[/tex]
Opening brackets,
[tex] = 54 {x}^{2} - 12x - 36x + 8[/tex]
Simplifying them we get,
[tex] = 54 {x}^{2} - 48x + 8[/tex]
Therefore, the answer is 54x^2 - 48x +8.
Hope it helps..
