Answer:
x2 + 8x - 3
Explanation:
1 . ((2x2 + 4) - 5) - (x2 - 8x + 2)
2. Factoring x2+8x-3
The first term is, x2 its coefficient is 1 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3
Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 8 .
Step 3. -3

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
So that the answer
