化简 (sqrt(4)+sqrt(3))^2

解答

化简

(4 + 3)^{2}

7 + 43

十进制

13.92820 \dots

求解步骤

(4 + 3)^{2}

使用完全平方公式:

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

(4 + 3)^{2} = (4)^{2} + 243 + (3)^{2}

= (4)^{2} + 243 + (3)^{2}

(4)^{2} + 243 + (3)^{2} = 7 + 43

= 7 + 43

f a c t or 6 x^{2} + 6 x + 12

s im pl i f y x (x^{3} \cdot x^{0})

f a c t or 6 x^{3} - 11 x^{2} - 4 x + 4

f a c t or - x^{3} - 75 x - 15 x^{2} - 125

f a c t or x^{4} - 7 x^{2}
