Question

Find 4-y, ( √4^½ )² - (4)² = y

Answer 1

I know your qquestion is very hard but I am trying.

➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡➡

➡➡y²-14y+49 + (y^½) = 11

➡➡Let a = y^½ then y = a²

➡➡a^4 - 14a² + 49 + a = 11

➡➡a^4 - 14a² + a + 38 = 0

➡➡(a-2)(a³+2a²-10a-19) = 0

➡➡a-2 = 0

➡➡a = 2

➡

Then y = a² = (2)² = 4

➡x = y²-14y+49 = 4²-14(4)+49

= 16-56+49

= 63-56

➡➡= 9

➡➡

Therefore, x = 9 and y = 4
