Expert Solution

Answer to Problem 48E

  v=12,3

Explanation of Solution

Given information:

  2v2+7v+3=0

Formula used:

Splitting the middle term:- in this method, middle term is splitted in such a way that the product of its part is equal to the product of constant and first terms coefficient.

Calculation:

  2v2+7v+3=0

Splitting middle term in such a way that product of its part is equal to product of constant and coefficient of first term.

  2v2+7v+3=02v2+6v+1v+3=02v(v+3)+1(v+3)=0(2v+1)(v+3)=0

  v=12,3
