Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history 3.2 Solving -x 2 +3x+10 = 0 by Completing The Square . Multiply both sides of the equation by (-1) to obtain positive coefficient for the first term: x 2-3x-10 = 0 Add 10 to both side of the equation : x 2-3x = 10 Now the clever bit: Take the coefficient of x , which is 3 , divide by two, giving 3/2 , and finally square it giving 9/4 Divide -3, the coefficient of the x term, by 2 to get -\frac{3}{2}. Then add the square of -\frac{3}{2} to both sides of the equation. This step makes the left hand side of the equation a perfect square.

you may certainly desire parentheses around the 3x-4 and x + 6 to sparkling up it the 2d way 2. Suppose that f(x) = (c(3x−x2) if 0 ≤ x≤ 2 0 otherwise is the probability density function of the random variable X. (a) Find c. Solution. We integrate and set this equal to 1. This gives us c= 3/10. (b) Find P{−1 ≤ x≤ 1}. Solution.
