Answer:
B) 11√3 - 7√6
Step-by-step explanation:
√48 can be simplified to <em>4√3</em>, and √54 can be simplified to <em>3√6</em>.
The equation is now <em>7√3 - 4√6 + 4√3 - 3√6</em>.
This can be grouped into <em>(7√3 + 4√3) + (-4√6 -3√6)</em>.
We get 11√3 - 7√6.
This equation has one solution which is -1.5
3x+7=-3x-2
+2. +2
3x+9=-3x
-3x. -3x
9= -6x
/-6. /-6
X= -1.5
Step-by-step explanation:
Since, x=8 and x=-5 are the roots.
Therefore, (x - 8) & (x - 5) will be factors.
Hence, required quadratic equation can be given as:

If x=mx-3 (which is not clear from your input),
3
then x-mx = -3, or mx-1x = 3, and x(m-1) = 3, and so x = ---------
m-1
