So 2x+4x+12=90

6x+12=90

6x=78

x=13

Find the condition that one root of the quadratic equation may be 1 more than the other.

Eddi Din [679]

Let p, np be the roots of the given QE.So p+np = -b/a, and np^2 = c/aOr (n+1)p = -b/a or p = -b/a(n+1)So n[-b/a(n+1)]2 = c/aor nb2/a(n+1)2 = cor nb2 = ac(n+1)2
Which will give can^2 + (2ac-b^2)n + ac = 0, which is the required condition.

then multiply 1 by 3 which is 3/15

subtract 3/15 from 10/15 which is 7/15
