Answer:

x = 6

See image.

Step-by-step explanation:

Logarithms are just another way to write exponents. The base on the logarithm that is the small font subscript IS the base (normal font/on the line) of an exponential equation. The "answer" in the logarithmic equation is the exponent (small font/superscript) .It is just a triple shuffle. When the logarithmic equation cant be worked on to solve it, CHANGE IT to exponential form. See image.

Answer:

b)

$x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}$

Step-by-step explanation:

<u>Step(i)</u>:-

Given quadratic equation ax² + bx + c = 0

<u>step(ii)</u>:-

ax² + bx = -c

<u>Step(iii):</u>-

Dividing 'a' on both sides , we get

$\frac{ax^{2} +bx }{a} = \frac{-c}{a}$

$x^{2} + \frac{bx}{a} = \frac{-c}{a}$

<u><em>Step(iv)</em></u>:-

Adding $(\frac{b}{2 a} )^{2}$ on both sides , we get

$x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}$
