expand (1-x)(1,3,-2)

expand

(1 - x) (1, 3, - 2)

1 \cdot 1, 3, - 1 \cdot 2 - 1 \cdot x, 3, 2 x

Solution steps

(1 - x) (1, 3, - 2)

= (1 \cdot 3,, - 2) (1 - x)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 1, b = - x, c = 1, 3,, d = - 2

= 1 \cdot 1, 3, 1 \cdot (- 2) + (- x) \cdot 1, 3, (- x) (- 2)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= 1 \cdot 1, 3, - 1 \cdot 2 - 1 \cdot x, 3, 2 x

\frac{81 ( 1 3 ^{15} - 1 )}{1 3 ^{15} \cdot 2}

2 (e^{2} - 3)

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

(- 2 a^{3})^{2}

\frac{( 4 x - 11 )}{( 2 x ^{2} + 7 x - 4 ) d x}
