How do you factor the polynomial 3x^2 + 8x^2 - x - 10 = 0?

x = 1 and x = -10/11

Step-by-step explanation:

3x² + 8x² - x - 10 = 0

11x² - x - 10 = 0

(11x + 10)(x - 1) = 0

11x + 10 = 0

11x = -10

x = -10/11

x - 1 = 0

x = 1

the answe i =−n+5

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
