Question

For what value of x is...

Answer 1

Answer:

• x = 6

Step-by-step explanation:

Set the equation and solve for x:

• (x + 1)² = (x - 3)² + 120
• x² + 2x + 1 = x² - 6x + 9 + 120
• 2x + 6x = 129 - 1
• 8x = 128
• x = 128/8
• x = 6

Answer 2

Lets , find the value of x :

$→(x + 1)² = (x - 3)² + 120$

$→x² + 2x + 1 = x² - 6x + 9 + 120$

$→2x + 6x = 129 - 1$

$→8x = 128$

$→x = \frac{128}{8}$

$→x = 6$
