What to do if quadratic equation has a negative spuare root?

alex41 [277]

If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be $3+\sqrt{5}$

then $3-\sqrt{5}$ will also be a solution.

To divide fractions, you multiply by the reciprocal of the second fraction.

kicyunya [14]

This is true.

Example:

= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3

= 8/9 * 3/7

= (8*3)/(9*7)
multiply numerators; multiply denominators

= 24/63
simplify

= 8/21

ANSWER: This is (A) true

Hope this helps! :)

Solve for a in terms of F and m: F=ma

Elena-2011 [213]

To solve for a, you must get a by itself on one side of the equation. Now, a is "joined" to m by multiplication. To "separate" them, use the inverse operation, division.

Divide both sides of the equation by m.

$F=ma \\ \frac{F}{m}=\frac{ma}{m} \\ \frac{F}{m}=a \\ a=\frac{F}{m}$
