X4 + 6x2 + 25 factorise

Step-by-step explanation:

Solution for x^4+6x^2+25=0 equation: 25 + 6x2 + -25 + x4 = 0 + -25 Reorder the terms: 25 + -25 + 6x2 + x4 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + 6x2 + x4 = 0 + -25 6x2 + x4 = 0 + -25 Combine like terms: 0 + -25 = -25 6x2 + x4 = -25 The x term is 6x2.

they go with it happens or they mite give a chance?

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
