4x egal cu 6_ _va rog raspuns rapid...dau coroana.
4

Answer 1

4x² = 6*1/4

4x² = 25/4

x² = 25/4 : 4

x² = 25/16

x = √(25/16)

x= + - (5/4) sau + - 1intreg1/4

Answer 2

$4x^{2} = 6 \frac{1}{4} \\ {4x}^{2} = \frac{25}{4} \\ {x}^{2} = \frac{25}{4} \div 4 \\ {x}^{2} = \frac{25}{4} \times \frac{1}{4} \\ {x}^{2} = \frac{25}{16} \\ x = \sqrt{ \frac{25}{16} } \\ x = + - \frac{5}{4} \\ \\ 4x = 6 \\ x = 6 \div 4 \\ x = \frac{6}{4} \\ x = \frac{3}{2}$
