Question

Solve for x in the equation x squared minus 12 x 36 = 90.

Answer 1

x = ±3√58

Explanation:

Given

• x² - (12 x 36) = 90

Solving

• x² - 432 = 90
• x² = 522
• x² = 9 x 58
• x = ±3√58

Answer 2

`x =` ±
`22.85`

Explanation:

Step 1: Multiply 12 * 36

`x^2 - (12 * 36) = 90`

`x^2 - 432 = 90`

Step 2: Add 432 to both sides

`x^2 - 432 + 432 = 90 + 432`

`x^2 = 522`

Step 3: Square root both sides

`√(x^2) = √(522)`

`x =` ±
`22.85`

Answer:
`x =` ±
`22.85`
