Question

Subtract 8x²-6x-5 from 6x²-9x+2and add x²-x-3 to the result​

Answer 1

Step-by-step explanation:

8x²-6x-5+6x²+9x-2=14x²+3x-7+(x²-x-3)=13x²+2x-10

Answer 2

Answer:

$6x²-9x+2 - (8x²-6x-5) \\ = 6x²-9x+2 - 8x² + 6x + 5 \\ = - 2 {x}^{2} - 3x + 7$

$- 2 {x}^{2} - 3x + 7 + {x}^{2} - x - 3 \\ = - {x }^{2} - 4x + 4 \\ or \\ = {x }^{2} + 4x - 4$
