I think the answer is (-a+10)(a+5)
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
(100 - 100 / 100 - 100) = 2 => 102 - 102 / 10(10 - 10) =2 => (10 + 10) (10 - 10) / 10(10 - 10) = 2 [a2 - b2 = (a + b) (a - b)] Cancelling ( 10 - 10 ) {numerator} from ( 10 - 10 ) {denominator} => ( 10 + 10 ) / 10 = 2 => 20 / 10 = 2 => 2 = 2 [Hence, Proved]
10
2 a2 is a monomial, not a binomial but 2 + a2 is a binomial, so is 2 - a2 .
