expand A(4,5)B(3,-2)C(1,-4)

expand

A (4, 5) B (3, - 2) C (1, - 4)

3 (4 \cdot 5,) A BC, 1, - 3 (4 \cdot 5,) A BC, 4 - 2 \cdot 1 \cdot (4 \cdot 5,) A BC, 2 \cdot 4

Solution steps

A (4, 5) B (3, - 2) C (1, - 4)

= (4 \cdot 5,) (3, - 2) (1, - 4) A BC

Expand

(3, - 2) (1, - 4) : 3, 1, - 3, 4 - 2 \cdot 1, 2 \cdot 4

= A (4, 5) BC (3, 1, - 3, 4 - 2 \cdot 1, 2 \cdot 4)

Expand

A (4, 5) BC (3, 1, - 3, 4 - 2 \cdot 1, 2 \cdot 4) : 3 (4 \cdot 5,) A BC, 1, - 3 (4 \cdot 5,) A BC, 4 - 2 \cdot 1 \cdot (4 \cdot 5,) A BC, 2 \cdot 4

= 3 (4 \cdot 5,) A BC, 1, - 3 (4 \cdot 5,) A BC, 4 - 2 \cdot 1 \cdot (4 \cdot 5,) A BC, 2 \cdot 4

(e^{5} + 9)^{2}

\frac{7 ( y ^{2} - x ^{2} )}{y + z + 1}

\frac{( x + 1 ) ^{2}}{( x - 1 ) ( x + 2 )}

(y = 2, x - 3) (y = 2 x^{2} + 5 x + 6)
