36 - y^2 = (√8 - a)(√8 + a) = (3√x + b)(3√x - b) = (8 + 3x)^2 = (7y + 5x)^2 = (25 - √x)^2
1) (√8 - a)(√8 + a) = 8 - a^22) (3√x + b)(3√x - b) = 9x - b^23) (8 + 3x)^2 = 64 + 48x + 9x^24) (7y + 5x)^2 = 49y^2 + 70xy + 25x^25) (25 - √x)^2 = 625 - 50√x + x
So, 36 - y^2 = 8 - a^2 = 9x - b^2 = 64 + 48x + 9x^2 = 49y^2 + 70xy + 25x^2 = 625 - 50√x + x
36 - y^2 = (√8 - a)(√8 + a) = (3√x + b)(3√x - b) = (8 + 3x)^2 = (7y + 5x)^2 = (25 - √x)^2
1) (√8 - a)(√8 + a) = 8 - a^2
2) (3√x + b)(3√x - b) = 9x - b^2
3) (8 + 3x)^2 = 64 + 48x + 9x^2
4) (7y + 5x)^2 = 49y^2 + 70xy + 25x^2
5) (25 - √x)^2 = 625 - 50√x + x
So, 36 - y^2 = 8 - a^2 = 9x - b^2 = 64 + 48x + 9x^2 = 49y^2 + 70xy + 25x^2 = 625 - 50√x + x
