Question

`\bf \huge x {}^(2) + 5 = 6`

solve for x :






`\tiny \textsf{Song recommendations \:? }~`
​

Answer 1

`x^2+5=6\\x^2=1\\x=1 \vee x=-1`

Answer 2

Given :

• x² + 5 = 6

Subtract 5 from each side :

• x² + 5 - 5 = 6 - 5
• x² = 1

Take the root on each side :

• √x² = √1
• x = ±1

Hence, the values of x are :

• 
  `\fbox {x = 1}`
• 
  `\fbox {x = -1}`
