Given that a polynomial P(x ) = x3 + mnx2 - 6x + n, where m and n are constants. 1 – 2 is a factor of P(x) and the remainder P(x) is 10. Calculate the value of m and n.

decimal: 0.25

fraction: ¼

Step-by-step explanation:

Think about it in decimal form first - 2/10 = 0.2 and 3/10 = 0.3

Halfway between them is the point. So, what is halfway between 0.2 and 0.3? If it makes it easier, write this as 0.20 and 0.30 - halfway between them is 0.25

Then just convert into a fraction - 25/100 = ¼
