solvefor x,T=(x+9)(x-9)-x^2

solve for

x, T = (x + 9) (x - 9) - x^{2}

True for all x; - 81 = T

Solution steps

T = (x + 9) (x - 9) - x^{2}

Switch sides

(x + 9) (x - 9) - x^{2} = T

Expand

(x + 9) (x - 9) - x^{2} : - 81

- 81 = T

Both sides are equal

True for all x; - 81 = T

C, y = C (1 + x)

\frac{6}{5} x + \frac{2}{7} = \frac{1}{35}

x, 3 y = 6 x + 12

2 \frac{1}{3} - \frac{1}{2} x = - \frac{2}{3}

y = 4 (1)^{2}
