Ответ:
Multiply both sides by 3 to isolate 2x².
2x² = 72
Divide both sides by 2 to isolate x².
x² = 36
Square root both sides to isolate x.
x = -6 or 6
-6 is smaller than 6.
The smallest solution is -6.
Ответ:
-1
f(2)= 2* 2 - 5 = -1
but if you meant f(x)=x²-5
its
f(2)=2²-5 = 4-5 = -1
it's indeed not the same for all other values of x, for example x=3!
