Question

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

Answer 1

Answer:

x = ±3√58

Step-by-step explanation:

Given

• x² - (12 x 36) = 90

Solving

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

Answer 2

Answer:

$x =$ ± $22.85$

Step-by-step 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

$\sqrt{x^2} = \sqrt{522}$

$x =$ ± $22.85$

Answer: $x =$ ± $22.85$
