8t^2 - 11t - 4
s+s2+s+32s2=2s+s2+32s2=2s+33s2I am pretty sure that that is the correct answer.
Factor the numerator. x+1 is one of its factors (otherwise, it wouldn't be possible to simplify it). Then cancel the identical factors in the numerator and the denominator.
3+2+3²-1 = 5+8-1=12
It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.
It is a polynomial expression in x. What about it?
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
3x^2 + x + 2x^2 = 5x^2 + x
(c + d)(c + d)
The answer is 258x
