1. Problem Description

We need to solve the provided equations for $x$. The equations are:

2

1. $x^2 = B$

2

2. $x^2 + A = B$

2

3. $x^2 - A = M$

2

4. $b = a + x^2$

2

5. $C - x^2 = m$

2

6. $n = d - x^2$

2

7. $mx^2 = n$

2

8. $b = ax^2$

2

0. $x^2 + 1 = 17$

1

9. $x^2 = g$

2. Solution Steps

2

0. $x^2 + 1 = 17$

Subtract 1 from both sides:

$x^2 = 17 - 1$

$x^2 = 16$

Take the square root of both sides:

$x = \pm \sqrt{16}$

$x = \pm 4$

2

1. $x^2 = B$

Take the square root of both sides:

$x = \pm \sqrt{B}$

2

2. $x^2 + A = B$

Subtract $A$ from both sides:

$x^2 = B - A$

Take the square root of both sides:

$x = \pm \sqrt{B - A}$

2

3. $x^2 - A = M$

Add $A$ to both sides:

$x^2 = M + A$

Take the square root of both sides:

$x = \pm \sqrt{M + A}$

2

4. $b = a + x^2$

Subtract $a$ from both sides:

$x^2 = b - a$

Take the square root of both sides:

$x = \pm \sqrt{b - a}$

2

5. $C - x^2 = m$

Subtract $C$ from both sides:

$-x^2 = m - C$

Multiply by -1:

$x^2 = C - m$

Take the square root of both sides:

$x = \pm \sqrt{C - m}$

2

6. $n = d - x^2$

Subtract $d$ from both sides:

$n - d = -x^2$

Multiply by -1:

$x^2 = d - n$

Take the square root of both sides:

$x = \pm \sqrt{d - n}$

2

7. $mx^2 = n$

Divide both sides by $m$:

$x^2 = \frac{n}{m}$

Take the square root of both sides:

$x = \pm \sqrt{\frac{n}{m}}$

2

8. $b = ax^2$

Divide both sides by $a$:

$x^2 = \frac{b}{a}$

Take the square root of both sides:

$x = \pm \sqrt{\frac{b}{a}}$

1

9. $x^2 = g$

Take the square root of both sides:

$x = \pm \sqrt{g}$
