expand (x-2)(x+5,0.5)

expand

(x - 2) (x + 5, 0.5)

xx + 5 x, 0.5 - 2 x - 2 \cdot 5, 0.5

Solution steps

(x - 2) (x + 5, 0.5)

= (x - 2) (x + 5 \cdot 0.5,)

Apply FOIL method:

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

a = x, b = - 2, c = x, d = 5, 0.5

= xx + x \cdot 5, 0.5 + (- 2) x + (- 2) \cdot 5, 0.5

Apply minus-plus rules

+ (- a) = - a

= xx + 5 x, 0.5 - 2 x - 2 \cdot 5, 0.5

(2 x + 1) \cdot e^{5}

\frac{( x + 2 ) ( x - 1 )}{( x - 5 ) ( x + 4 )}

\frac{q ^{6}}{q ^{4}}

4 - 2 ln (8)

\frac{3 s + 4}{( s + 1 ) ( s + 2 )}
