Transcribed Image Text:Simplify the problem and write in standard form.
(-6x² + 9x-7)+(10x²-5x-1)-(2x + 3)²

Transcribed Image Text:(2x-3)^3=(2x-3)(2x-3)(2x-3)

Answer: 8x^3-
36x^2+54x-27
(3x² - 9x + 5) + (8x - 5) - (5x-9)²
(3x²-9x +S) +(8x-5) −(25x²90x+1)
(3x²-x) - (25x²-90x +81)
3x²-x-25x² +90x-81
* −23x²+89x-81*
