Answer:
x³ - 10x² + 31x - 30
Step-by-step explanation:
Given
(x - 2)(x - 3)(x - 5) ← expand the second pair of factors using FOIL
= (x - 2)(x² - 8x + 15) ← distribute
= x³ - 8x² + 15x - 2x² + 16x - 30 ← collect like terms
= x³ - 10x² + 31x - 30
A. 2x^5+4x^3+2x-1
---------------------
(x^2+1)^2
B. 4
--------------
(x-1)^2(x+1)
The decimal number is 0.9
