Answer 1

Answer:

3x1/2 ANS

Step-by-step explanation:

2x ➕ x= 3x

2/4 =1/2

Answer 2

Answer:

Hey Mate.........

2x ^ + x + 4 = 0

Dividing throughout by 2 we get ,

x^ + x /2 + 2 = 0

Adding and Subtracting the square of half of the Coefficient of x/2

x^ + x/2 + 2 + [1/4 ] ^ - [1/4 ] ^ = 0

[x + 1/4 ]^ + 2 - [ 1/4 ] ^ = 0

[x + 1/4 ]^ + 2 - 1 / 16 = 0

[x + 1/4 ]^ + (32 - 1 / 16 ) = 0

[x + 1/4 ]^ + 31 / 16 = 0

[x + 1/4 ]^ + [ √31 / 4 ] ^ = 0

[x + 1/4 ]^ = - [ √ 31 / 4 ] ^

Since, [x + 1/4 ]^ Cannot be negative for the value of x. So there is no real Zero for this equation.

Hope it Helps u !
