Strictly speaking, x^2 + 2x + 4 doesn't have solutions; if you want solutions, you must equate <span>x^2 + 2x + 4 to zero:
</span>x^2 + 2x + 4= 0. "Completing the square" seems to be the easiest way to go here:
rewrite x^2 + 2x + 4 as x^2 + 2x + 1^2 - 1^2 = -4, or
(x+1)^2 = -3
or x+1 =i*(plus or minus sqrt(3))
or x = -1 plus or minus i*sqrt(3)
This problem, like any other quadratic equation, has two roots. Note that the fourth possible answer constitutes one part of the two part solution found above.
Answer:
the total will be 1
Step-by-step explanation:
ok so the denomitor are matching so you can add straight across

Step-by-step explanation:
when the difference between CI and SI given then the sum =
difference (100/r)^2
given difference is Rs . 180
Rate of interest is 15%
sum = 180× (100/15)^2
180×10000/225
= 8000
