無理方程式・不等式 演習3

√ ( x + 1 ) < 4 - 2x

 √ ( x + 3 ) = x + 1

√ ( x + 2 ) - √ ( 3 - x ) = 1

√ ( 2x + 4 ) > -x + 10

√ ( x + 1 ) = 2x - 4

√ ( 1 - 2x )  - √ ( 1 + 2x ) = 1

√ ( -x + 2 ) < x + 2 

√ ( x + 1 ) = 4 - 2x

√ ( 4x + 1) - 2√ ( 1 - x ) = 1

√ ( 3 - x ) = x + 3

√ ( 3 - x ) < x + 3

2√ ( x - 1 ) ≧ (1/2)x + 1

3√ ( 3 - 2x ) + 2x - 3 = 0

3√ ( 3 - 2x ) + 2x - 3 ≧ 0

√ ( x + 3 ) = | 2x |
