Expert Solution

Answer to Problem 52E

  x=3,3

Explanation of Solution

Given information:

  3x227=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:

  3x227=03x2+0x27=0

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

  3x2+0x27=03x29x+9x27=03x(x3)+9(x3)=0(x3)(3x+9)=0

  x=3,93x=3,3
