Why do we have this nagging feeling that the questioner isn't completely
sure of what the question is ?
We shall now take the given equation and find the numerical value
that 'x' must have in order to make the equation a true statement:
5 + x = 2x - 3
Add 3 to each side: ---> 8 + x = 2x
Subtract x from each side: ---> 8 = x
Not necessarily.
whats the answer for -2x^3+2^2+12x
It depends on whether or not there are parentheses around the 2x3. If yes, the answer is 26. If not, the answer is 48.
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156

Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
This question can only be answered if the probability distribution functions of X1, X2 and X3 are known. They are not and so the question cannot be answered.
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
2x3 + 4 = 17 2x3 = 13 x3 = 13 / 2 x = (13 / 2)1/3 x = 521/3 / 2
