expand (x-9)(4x-8(=0))

expand

(x - 9) (4 x - 8 (= 0))

4 xx - 8 (0 =) x - 9 \cdot 4 x + 9 \cdot 8 (0 =)

Solution steps

(x - 9) (4 x - 8 (= 0))

= (x - 9) (4 x - 8 (0 =))

Apply FOIL method:

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

a = x, b = - 9, c = 4 x, d = - 8 (= 0)

= x \cdot 4 x + x (- 8 (= 0)) + (- 9) \cdot 4 x + (- 9) (- 8 (= 0))

Apply minus-plus rules

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

= 4 xx - 8 (0 =) x - 9 \cdot 4 x + 9 \cdot 8 (0 =)

\frac{1}{( x + 8 ) ^{3}}

\frac{( y - 1 ) ^{2}}{4}

\frac{( a ^{2} + 81 )}{x ( a + 9 ) ^{2}}

\frac{s - 4}{38 ( s ^{2} + 3 s + 10 )}

(c^{2} + d^{2}) (e^{2} + f^{2})
