Find the error in the calculations below, if there is one:

Between line 1 and 2

Step-by-step explanation:

4x³ +2x²- 6x+ 3     (Line 1)

note that +3 can be written as  -(-3), giving us:

4x³ +2x² -6x - (-3)

if we group the first two terms and the last two terms, we will get

(4x³ +2x²) + [ -6x - (-3) ]   (factor out 2x from first group and -3 from second group)  

= 2x²(2x +1) -3(2x - 1 )

if we compare this with (Line2) we can see that the difference is in the sign of the last term inside the second group. Hence this is where the mistake is made Between line 1 and 2

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female
