Answer:
x² + 4y² = 32 , 2x+y-1=0
To Find : Points of intersections
Solution:
x² + 4y² = 32
2x + y - 1 = 0
=> y = 1 - 2x
x² + 4y² = 32
x² + 4(1-2x)² = 32
=> x² + 4(1 + 4x² - 4x) = 32
=> x² + 4 + 16x² - 16x = 32
=> 17x² - 16x - 28 = 0
=> x = (16 ± √16² - 4(17)(-28) )/2(17)
=> x = (16 ± 12√15 )/2(17)
=> x = (8 ± 6√15)/17
y = 1 - 2x
=> y = 1 - 2 ( (8 ± 6√15)/17)
=> y = (17 - (16 ± 12√15) )/ 17
Intersection Points are :
(8 + 6√15)/17 , (1 - 12√15)/17 )
(8 - 6√15)/17 , (1 + 12√15)/17 )
