What is the positive solution to the equation 0 = -x2 + 2x + 1?
quadratic formula: x= -b
b2 - 4ac
2a
0 - 2 + √2
02-2
o 1+2
0 –1 + √2

if this is really you s much. i only have 3 points left and i have 2 questions to ask

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
