solvefor x,x(2x+1)=0

解答

求解

x, x (2 x + 1) = 0

解答

x = 0, x = - \frac{1}{2}

+1

十进制

x = 0, x = - 0.5

求解步骤

x (2 x + 1) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or 2 x + 1 = 0

解

2 x + 1 = 0 : x = - \frac{1}{2}

二次方程组的解是:

x = 0, x = - \frac{1}{2}

6x^2+125=5(x^2+25)

6 x^{2} + 125 = 5 (x^{2} + 25)

4 x^{2} + 5 x = - 1

9(x^2-2)-13=-15

9 (x^{2} - 2) - 13 = - 15

(17-y)^2+y^2=145

(17 - y)^{2} + y^{2} = 145

5(3x+8)^2-16=29

5 (3 x + 8)^{2} - 16 = 29
