簡約 (sqrt(x-5))*(3x+6)

解

簡約

(x - 5) \cdot (3 x + 6)

(3 x + 6) x - 5

解答ステップ

(x - 5) (3 x + 6)

規則を適用する:

(a) = a

(x - 5) = x - 5

= x - 5 (3 x + 6)

= (3 x + 6) x - 5

e x p an d (10 - 2) 3 + 5

e x p an d (1 + cos (t)) cos (\frac{t}{2}) + sin (t) sin (\frac{t}{2})

e x p an d (5 sec (θ) + 2)^{2}

e x p an d lo g_{10} (3) (x + 2)

e x p an d \frac{( x - 1 ) ( x - 2 ) ( x - 3 )}{( 0 - 1 ) ( 0 - 2 ) ( 0 - 3 )}
