in triangle ABC trangle represent the area of trianle then COT B+COT c
2x - y + 6z - a = 7
2y + z + 7a = 8
x + y + 3z + 4a = 8
-x -2y + 3z - a = 1
7*-16/13-4
P(x)= $2x^{2}$+4x-48
(32x^3 - 4x^2 + 3x - 23) ÷ (8x - 7)
3*-16/13+5/2
P(x)= $a2x^{2}$+4x-48
-8 divided by 13/2
\frac{1}{12}x^{2}+\frac{1}{3}x^{7}-\frac{1}{6}x^{9}
