here is yoir process dear......

(2-3x) (5-2x)

= 10 -4x-15x-+6x²

= 10-19x +6x²

(so the coefficient of x is -19)

The coefficient of x is - 19

Given :

The expression (2 - 3x)(5 - 2x)

To find :

The coefficient of x in (2 - 3x)(5 - 2x)

Concept :

Coefficients :

In a term of an algebraic expression the numerical factor of a term is called coefficients and any of the factors with the sign of the term is called coefficient of the product of the other factors

Solution :

Step 1 of 3 :

Write down the given expression

Here the given expression is (2 - 3x)(5 - 2x)

Step 2 of 3 :

Simplify the given expression

\displaystyle \sf{(2 - 3x)(5 - 2x)  }

\displaystyle \sf { = 2(5 - 2x)  - 3x(5 - 2x)  }

\displaystyle \sf { = 10- 4x - 15x  + 6 {x}^{2} }

\displaystyle \sf { =  6 {x}^{2}   - 19x + 10}

Step 3 of 3 :

Find the coefficient of x in the expression

The term involving x is - 19x

We know that in a term of an algebraic expression the numerical factor of a term is called coefficients

Hence the coefficient of x in the expression is - 19
