Answer:
x=0
x=12
Step-by-step explanation:
Set up the equation
x^2-12x=0
Factor out x
x(x-12)=0
Set each factor equal to 0.
x=0
(x-12)=0
x=12
You can think of the absolute value as the distance from 0.
10 and -10 are both 10 units away from 0.
Explanation;
To solve an exponential Equation with different bases we need to the following steps;
1. Isolate the exponential part of the equation. If there are two exponential parts put one on each side of the equation.
2^x=3^x+1
2. Introduce logarithm of each side of the equation;
log 2^x = log 3^x+1
3. Then apply power property to rewrite the exponent.
x log 2= (x+1)log 3
4. Then Solve for the variable ;
x log 2 = log 3 + x log 3
x log 2 - x log 3 = log 3
x (log 2 - log 3) = log 3
and x = log 3 / (log 3 - log 2)
Answer:
x^2 +x+2
Step-by-step explanation:
f(x) = x^2+3
g(x) = x-1
f(x)+ g(x) = (f+g) (x)
x^2+3+ x-1
x^2 +x+2
