Solve F=D+Drt for t.....
Anuta_ua [19.1K]

Answer:

t = \frac{-D+F}{Dr}

Step-by-step explanation:

Step 1: Flip the equation.

  • Drt + D = F

Step 2: Subtract D from both sides.

  • Drt + D - D = F - D
  • Drt = -D + F

Step 3: Divide both sides by Dr.

  • \frac{Drt}{Dr} = \frac{-D+F}{Dr}
  • t = \frac{-D+F}{Dr}

When completing the square, what value must you add to both sides of the equation to create a perfect square trinomial?
Sergeu [11.5K]
Notice that half of the coefficient of x is (1/2)(-4), or -2.

Then x^2 - 4x   becomes
         x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4.   Then x = -2 plus or minus 2, and the two roots are 0 and -4.

Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
