Solve -x^2 + 4x +10 = 0 by using the "Solving the square method"

Pavel [41]

Answer:

$x = - 2 + \sqrt{14} \: \: or \: \: x = - 2 - \sqrt{14}$

Step-by-step explanation:

${x}^{2} - 4x - 10 = 0 \\ {x}^{2} - 4x = 10 \\ {x}^{2} - 2(2x) = 10 \\ {x }^{2} - 2(2x) + 4 = 10 + 4 \\ {(x + 2)}^{2} = 14 \\ x + 2 = \sqrt{14} \: \: \: \: or \: \: \: x + 2 = - \sqrt{14}$

Christian and Tanae both leave Disneyland at the same time. Christian travels north at 65 mph. Tanae travels south at 55 mph. Ho

liq [111]

Answer:

Step-by-step explanation:

B looks like it would work.

You add speeds * time when you are travelling in opposite directions.

I don't know why you would add or subtract 1 as in A and C

120 * t = 540

t = 540/120

t = 4.5 hours.

So after 4.5 hours they are 540 miles apart.
