Explanation

The degree of a polynomial = the highest power of x.

In 2kx² − x + 1:  

2kx² has x² → power 2  

x has x¹ → power 1  

1 has x⁰ → power 0

Highest power = 2

√4x-3=4

Squaring both sides:

4x−3=16
$$4x=19$$x=19​/4=4.75

Explanation

If the determinant $|A|\ne 0$, then $A$ is non-singular (invertible), so the homogeneous system $AX=0$ has only the trivial solution $X=0$.

Given:

Since:

Multiplying both sides by: (x+1)(x2−x+1):

Expanding:

Comparing coefficients:

From $A+C=1$:

Substitute into the second equation:

Explanation

LCM of 3 and 4 = 12

1/3​=4/12​
1/4​=3/12​

Now add:

= 4/12 +3/12

=7/12

Explanation

Explanation

Since a > b > 0, a is greater than b, and both numbers are positive.

Therefore, a > b is correct.

Explanation

(x+7) x 3-5/ 4 = 7 

3 ( x+7) - 5 = 7 x 4 

3x + 21 -5 = 28 

3x + 16 = 28 

3x = 28 -26 

3x = 12

x = 12/3

x = 4
