Solve the equation x^2-4x-9=29
PtichkaEL [24]

Answer:

x² - 4x - 9 = 29

x² - 4x - 9 - 29 = 0

x² - 4x - 38 = 0

Using the quadratic formula

x =  \frac{ - b± \sqrt{ {b}^{2} - 4ac }  }{2a}

Where

a = 1 , b = -4 c = - 38

So we have

x =  \frac{ -  - 4± \sqrt{ { - 4}^{2}  - 4(1)( - 38)} }{2(1)}  \\  \\ x =  \frac{4± \sqrt{16 +152 } }{2}  \\  \\ x =  \frac{4± \sqrt{168} }{ 2}  \\  \\ x =2 ± \sqrt{42}  \\  \\  \\ x = 2 +  \sqrt{42}  \:  \:  \: or \:  \:  \: x = 2 -  \sqrt{42}

Hope this helps you
