Question

X² - 9/16 =0
x² - 1/4 =0
x² = 49/64
4x² - 2 = 0
4x² - 9 = 0
100x² - 25 = 0
100 x² - 50 = 0​

Answer 1

Explicación paso a paso:

1. ${16x}^{2} - 9 = 0 \\ {16x}^{2} = 9 \\ {x}^{2} = \frac{9}{16} \\ x = \frac{ + }{ } \frac{3}{4}$
2. x= ± 1/2
3. x=7/8
4. x=± √2/2
5. x= ± 3/2
6. x= ± 1/2
7. x= ± √2/2
