Answer:

[tex]x = -0.8\ or\ x = 0.5[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]6x^2 + 2x - 2.5 = 0[/tex]

Required

Solve

Using factorization, we have:

[tex]6x^2 + 2x - 2.5 = 0[/tex]

Expand 2x

[tex]6x^2 - 3x+5x - 2.5 = 0[/tex]

Factorize

[tex]3x(2x - 1)+2.5(2x - 1) = 0[/tex]

Factor out 2x - 1

[tex](3x +2.5)(2x - 1) = 0[/tex]

Split:

[tex](3x +2.5) = 0\ or\ (2x - 1) = 0[/tex]

In both cases, solve for x

[tex]3x = -2.5\ or\ 2x = 1[/tex]

[tex]x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}[/tex]

[tex]x = -0.8\ or\ x = 0.5[/tex] --- approximated
