化简 (4x+3)(x-sqrt(3))(x+sqrt(3))

解答

化简

(4 x + 3) (x - 3) (x + 3)

(4 x + 3) (x^{2} - 3)

求解步骤

(4 x + 3) (x - 3) (x + 3)

使用平方差公式:

(a - b) (a + b) = a^{2} - b^{2}

(x - 3) (x + 3) = x^{2} - (3)^{2}

= (4 x + 3) (x^{2} - (3)^{2})

化简

x^{2} - (3)^{2} : x^{2} - 3

= (4 x + 3) (x^{2} - 3)

e x p an d (4 cos (x) + 1) (4 cos (x) - 1)

e x p an d a (cos (φ) + φ sin (φ))

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

e x p an d, 2 (7 + 5)

e x p an d (9 e^{x} - 7) (8 e^{x})
