Simplify.

Alika [10]

Solution:

Note that:

Given expression: (x² + 4x) − (x² + 6x − 3)

Remove the brackets

(x² + 4x) − (x² + 6x − 3)
=> x² + 4x - x² - 6x + 3

Combine like terms

x²(1 - 1) + x(4 - 6) + 3
=> x²(0) + x(-2) + 3
=> -2x + 3

Make x the subject of the formula for Q20.

saul85 [17]

Answer:

$x = \sqrt{m(\frac{a}{b})^{2} +n }$

Step-by-step explanation:

$a\sqrt{(\frac{x^{2} - n }{m}) } = \frac{a^{2} }{b}$

$\sqrt{\frac{x^{2} - n }{m} } = \frac{a}{b}$ [Divide both sides by $a$ ]

$\frac{x^{2} - n}{m} = (\frac{a}{b} )^{2}$ [Square both sides]

$x^{2} -n = m(\frac{a}{b} )^{2}$ [Multiply both sides by m]

$x^{2} =m(\frac{a}{b} )^{2} + n$ [Bring n to the right]

$x = \sqrt{m(\frac{a}{b})^{2} +n }$ [Square root both sides]
