Please use " ^ " to denote exponentiation:  2x^2 − 5x − 3

Rather than try to factor this from scratch, test the given factors in the possible answers.  Looking at the fourth possible answer (D), we see that two criteria are satisfied:  (1) the product of +1 and -3 is -3, which equals the third term of the given polynomial, and (2) +1x - 6x = -5x, which equals the second term.  Thus,

2x^2 − 5x − 3 =  (2x + 1)(x − 3)

It should be noted that in rounding the  a number up, it is required to look at the next digit at the right hand of the given figures in a case whereby the digit is less than 5,the digit can be rounded down, but in the case whereby the digit is more that 5 then it can be rounded up .

From the given values, we are given the 990,201 and 159,994  and if this were to rounded up to the nearest 10 thousand then we will start from the right hand sides and round down the values less than 5 and round up the values that is more that 5. and their values will be 990000

and 150000.
