Answer:
[tex]x= +-\frac{7}{4}[/tex]
Step-by-step explanation:
[tex]16x^2= 49[/tex]
Solve the equation for x
To solve the equation , we need to isolate x
To get x alone , we need to remove the numbers attached with x
To remove 16 we divide both sides by 16
[tex]x^2 = \frac{49}{16}[/tex]
Now to remove square from x we take square root on both sides
[tex]\sqrt{x^2} = \sqrt{\frac{49}{16}}[/tex]
square root (49) = 7
square root (16)= 4
So , [tex]x= +-\frac{7}{4}[/tex]
When we take square root we include +-
