Answer:
x = 12
Step-by-step explanation:
5+x2 = 2x2+13
5+x2 = 4+13
5+x2÷2 = 17
5-5+x = 17-5
x = 12
Answer:
0.25
Step-by-step explanation:
Answer:
The answer is 84.
Step-by-step explanation:
The given equation is
4x*2 + 2x -5 = 0
Here a= 4, b= 2, c= -5
Since Discriminant= b*2 -4ac
Putting values
Discriminant= (2)*2 - 4(4)(-5)
= 4 + 80
= 84
Since our Discriminant(84) is >0 and is not a perfect square so the roots of the given equation are unequal and irrational(real).
