Solve for x in the equation x2 + 4x-4=8.
iren [92.7K]

{x}^{2}  + 4x - 4 = 8 \\  =  >  {x}^{2}  + 4x - 4 - 8 = 0 \\  =  >  {x}^{2}  + 4x - 12 = 0 \\  =  >  {x}^{2}  + 6x  - 2x - 12 = 0 \\  =  >  x(x + 6) - 2(x + 6) = 0 \\  =  > (x - 2)(x + 6) = 0 \\  =  > x = 2 \:  \:  \: or \:  \:  \: x =  - 6

<u>Answer</u><u>:</u>

The lines x=0, y=2x-5, and y=mx+9 form a right triangle. find the two possible values of m
Alex17521 [72]

Answer: -1/2, 0

Step-by-step explanation:

x=0 , y=2x-5 and y=mx+9 form a right angle. So, y=mx+9 is either perpendicular to x=0 or y=2x-5 because the angle between x=0 and y=2x-5 is not 90 degrees. The product of slopes of perpendicular lines equals to -1.

Thus, m=-1/2 if it is perpendicular to y=2x-5. And y=c, for some constant if it is perpendicular to x=0. So y=0x+9 fits the bill. (m=0, in this case)
