Question

simplify (x^2-2×+3)(x-5)-(x+3)(2x^2-5x)​

Answer 1

( x ² - 2 x + 3 ) ( x - 5 ) - ( x + 3 ) ( 2x ²- 5 x )

( x ² - 6 ) ( x - 5 ) - ( x + 3 ) ( 2x ² - 5x )

x ³- 5x ²- 6x + 30 - ( x + 3 ) ( 2x ² - 5x )

x ³ - 5x ²- 6x + 30 - ( 2x ³ + x ² - 15 x )

x³ - 5 x ² - 6 x + 30 - 2x ³ - x ²

- x ³ - 5x ² - 6x + 30 - x ² + 15 x

- x ³ - 6x ² - 6x + 30 + 15 x

- x ³ - 6x ² + 9x + 30
