Solve: 12^x2+5x-4 =12^2x+6
lyudmila [28]

Answer:

x=2, x=-5

Step-by-step explanation:

to work more comfortably, the first thing we need to do is work the equation linearly, for that we take advantage of the property of logarithms that tells me that log(a^{b})=b*log(a)

in this way, the equation remains as:

log(12^{x^{2} +5x-4 } )=log(12^{5x+6} ) \\ (x^{2} +5x-4 )*log(12)=(5x+6) *log(12)\\x^{2} +5x-4 = 5x+6

Now we clear the equation so that it is of the form ax^{2} +bx+c=0

x^{2} +5x-2x=6+4\\ x^{2} +3x-10=0

finally, we apply the equation to solve second degree equations

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

x = \frac{-3 \pm \sqrt {3^2-4*1*(-10)}}{2*1}\\ x = \frac{-3 \pm \sqrt {9+40}}{2}\\ x = \frac{-3 \pm 7}{2}

x=2 and x=-5

Done
