Answer
$-x^2-8x-47$.
Work Step by Step
The given expression is
$=(3x+5)(2x-9)-(7x-2)(x-1)$
In each operation multiply the second bracket by each term of the first bracket as shown below.
$=3x(2x-9)+5(2x-9)-[7x(x-1)-2(x-1)]$
Clear the parentheses.
$=6x^2-27x+10x-45-[7x^2-7x-2x+2]$
Simplify.
$=6x^2-17x-45-[7x^2-9x+2]$
$=6x^2-17x-45-7x^2+9x-2$
$=-x^2-8x-47$.
