3+2+3²-1 = 5+8-1=12
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.
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?
5^0+4^2=? 5^0=1 4^2=16 So, 1+16=17 Answer is 17.
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
208,000,000
(c + d)(c + d)
The answer is 258x
The lack of bracketing here makes it impossible to know how all these operations are grouped. For example does the first bit mean (5x5/x2)+7x.. or does it mean 5x5/(x2+ 7x).. and so on for other ambiguities?
