Question

1. Verify whether 2 and 0 are zeroes of the polynomial x2-2x
2. evaluate 101³
thx in advance

Answer 1

(100+1) cube = 101cube

by applying identity of (a + b)cube we get

1000000+1+30000+300

add it and yu will get the answer.

Answer 2

${x}^{2} - 2x = 0 \\ x(x - 2) = 0 \\ x = 0 \: \: \: \: or \\ \: x - 2 = 0 \\ x = 2$
