log4(x2+6x+11)=1/2

introvert2:
log4(x2+6x+11)=1/2

X = -3

AdeniyiA:


X = 3

pls,show your workings.thank you.

my workings, not sure if its correct.x2+6x+11=4^1/2. x2+6x+11=2. x2+6x+9=0. x2+3x+3x+9=0. x(x+3)+3(x+3)=0. x=-3twice.

Sorry x4 = -3-j2 ,correct this please

Very simple

See how I dey look this thing like say I no go school

God EPP us

Sorry x4 = -3-j2 ,correct this please

After your long tin, u still failed it

AdeniyiA:


After your long tin, u still failed it

tell me how i fail it dnt u see that the equation is not ordinary quadratic equation and even the RHS eqn of urs is not a perfect square before collecting like term,i think op should provide ans from where the question comes from

Helinus, Omenka and their fellow mofos will be dodging this thread like...

AdeniyiA:


X = -3

Correct

.

Both the question and the answers look somehow to me
Abeg which on is quadratic formula abi wetin e be seff

.

:pls,show your workings.thank you.Very simple

follow this

Oboy! Na 3 fullscap sheet you take solve the math

The first guy that solved it....just make a simple question so complicated....Haba
From log to quadratic enter polynomials divert to .........

Such people make maths unattractive and uninteresting to many people
And maths is the simplest subject I know

my workings, not sure if its correct.
x²+6x+11=4^½. x²+6x+11=2. x²+6x+9=0. x²+3x+3x+9=0. x(x+3)+3(x+3)=0. x=-3twice.

this one is absolutely correct!
