If the LCM of 12 and 42 is 10m +4, then the value of m is

If α and β are the zeros of the quadratic polynomial f(x) = x2 - px + q, prove that a2/b2 + b2/a2 = p4/q2 - 4p2/q + 2

Given thatαandβare the zeroes of the quadratic polynomialf(x) =x^{2}–px+q

What Is Formula For Alpha minus Beta

(α-β)?

N is a natural number such that when N^{3} divided by 9 ,it leaves remainder a.It can be concluded that

a)a is a perfect square b) a is a perfect cube c) both of these d ) none of these

There are 3 consecutive traffic lights which turn "green" after every 36, 42 and 72 seconds. They all were at "green" at 9:00 AM. At what time will they all turn "green" simultaneously?

αandβare the zeroes of the quadratic polynomialf(x) =x^{2}–px+qIn the given solution how did (a^{2}+ b^{2})^{2}- 2a^{2}b^{2}/ a^{2}b^{2 }changed into [(a + b)^{2}- 2ab ]^{2 }- 2(ab)^{2}/ (ab)^{2}i didnt understand how -2a^{2}b^{2}/ a^{2}b^{2 }change to^{}- 2(ab)^{2}/ (ab)^{2 }bcoz a^{2}b^{2}and (ab)^{2}are two different things. I guess !!i m confused..plzz help...What Is Formula For Alpha minus Beta
