42. Use the Quadratic Equation to find the Roots of x2 + 3x - 3=0
almond37 [142]

Answer:

Step-by-step explanation:

The coefficients of the x terms are {1, 3, -3}, so the discriminant, b^2 - 4ac, is 3^2 - 4(1)(-3), or 9 + 12, or 21.  The positive nature of the discriminant tells us that there are two real, unequal roots.  Following the quadratic formula, we get:

       -3 ± √21

x = -----------------

              2

3•f(-4)-3•g(-2)=?<br> Help please
Scilla [17]

Answer:

3⋅f(−4)−3⋅g(−2) = −12f+6g

Step-by-step explanation:

Write the problem as a mathematical expression.

3⋅f(−4)−3⋅g(−2)

Move − 4 to the left of f .

3⋅(−4⋅f)−3⋅(g(−2) )

Multiply−4 by 3.

−12f−3⋅(g(−2) )

Move − 2 to the left of g .

−12f−3⋅(−2⋅g)

and lastly Multiply−2 by −3.

−12f+6g

Hope this helps you out.
