The value of x is x
and x
Step-by-step explanation:
Factorisation is not possible in this case since the 2 pairs available will not be giving the same outcome as required in factorisation.
This is a quadratic equation
x² + x² – 3x – 3 = 0
2x² - 3x - 3 = 0
<u>Quadratic formula:</u>
a=2
b= -3
x= -3
= 
= 2.186
or
= 
= -0.686
Therefore, the value of x is,
x and x

Answer:
John is currently 6 years old.
Step-by-step explanation:
2 years ago: x years
Current time: x+2
In 6 years: x+8
EQUATION:
3(x)=x+8= 3x=x+8
(subract x from both sides)
2x=8
x=4
Therefore, John is 6 years old in current time
