Hi, i need to calculate roots x1 and x2 using the vieta theorem, can anyone help me? I have found the answer (1,5 ;2), all i need is a solution on how to get this answer, the equation is in the picture, will give you brainliest if you type down the correct solution for me, thanks.

Please answer my question

  x = 3/2 or 2

Step-by-step explanation:

Essentially, what you're looking for is a pair of factors of (-2)(-6) = 12 that have a sum of 7. The factors 3 and 4 have that sum, so we can write ...

  -2x² +3x +4x -6 = 0

  x(-2x+3) -2(-2x+3) = 0

  (x -2)(-2x +3) = 0

The roots are the values of x that make these factors zero.

  x -2 = 0   ⇒   x = 2

  -2x +3 = 0   ⇒   x = 3/2

These are consistent with Vieta's theorem, which tells you the sum of roots is -b/a = -7/-2 = 7/2. The sum of the two roots we found is 4/2 +3/2 = 7/2.

The product of roots is c/a = -6/-2 = 3. The product of the two roots we found is 2(3/2) = 3.

Additional comment

I find it easier to find integer factors of integers than to find fractional factors of an integer. The direct use of Vieta's theorem would have you looking for factors of 3 that have a sum of 7/2. It seems easier to me to look for integer factors of 12 that have a sum of 7.

the answer is a

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
