​

Answer 1

Answer:

5 is the constant

Step-by-step explanation:

5x²-2x+5=0

Answer 2

Answer:

=-1352

Step-by-step explanation:

By binomial theoremBy binomial theorem

(a+x)n=∑m=0n(nm)an−mxm(a+x)n=∑m=0n(nm)an−mxm

Replacing a by 3 x, x by−12xand n by 6Replacing a by 3 x, x by−12xand n by 6

(3x−12x)n=∑m=06(6m)(3x)6−m(−12x)m(3x−12x)n=∑m=06(6m)(3x)6−m(−12x)m

For middle term m = 3For middle term m = 3

middle term=(63)(3x)3(−12x)3middle term=(63)(3x)3(−12x)3

=6!3!×3!(27x3)(−18x3)=6!3!×3!(27x3)(−18x3)

=−1352
