如果不懂,请Hi我,祝学习愉快!

回答2:

1.x的(3)= 0
= 0或x 3 = 0

x = 0时或x = -3

2。

5倍2-2x的= 0

×(5倍,2)= 0

x = 0或5倍,2 = 0

x = 0时或x = 2/5 p>√2×2 = 4倍?

√2×2-4 = 0

×(√2倍-4)= 0

x = 0或√2倍,4 = 0

x = 0时或x = 2√2

4

×2 5的X 6 = 0

(-1),(X +6 )= 0

X-1 = 0或x +6 = 0

X = 1或x = -6

如果你不知道,你好,我,我想一个快乐学习!

回答3:

x(x+3)=0

5x²-2x=0
x(5x-2)=0
x=0或x=2/5

√2x²=4x
√2x²-4x=0
x(√2x-4) =0
x=0或x=2√2

x²+5x-6=0
(x+3)(x-2)=0

回答4:

x(x+3)=0

x=0或x+3=0
x1=0, x2=-3

5x的2次方-2x=0

x(5x-2)=0
x1=0, x2=0.4

根号2x的2次方=4x

2x²=16x²
14x²=0
x=0
x的2次方5x-6=0 漏符号了
