How many roots does the equation 3x² = 1 - 7x have and what is the nature of the roots

Mathematics
1 answer:
AnnyKZ [126]2 years ago
7 0

Answer:

Step-by-step explanation:

Rewrite this quadratic in standard form:  3x^2 + 7x - 1.

The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or

7^2 - 4(3)(-1), or 49 + 12, or 61.  Because the discriminant is positive, this quadratic has two real, unequal roots

−cz+6z=tz+83 solve for z
nasty-shy [4]
To answer this item, we combine all terms involving the variable z to only one side of the equation. All else will be placed on the other side of the equation. This is as follows,

   -cz + 6z = tz + 83

Transposing,
   -cz - tz + 6z = 83

Factoring z out,
  z(-c - t + 6) = 83

Dividing the equation such that z will be left on one side of the equation,
   
<em>  z = 83 / (-c - t + 6)</em>
