Solve the quadratic equation using any method. Round to the nearest tenth if neccessary. Any Help Is Appreciated
AVprozaik [17]

Answer:

x = -0.8\ or\ x = 0.5

Step-by-step explanation:

Given [Missing from the question]

6x^2 + 2x - 2.5 = 0

Required

Solve

Using factorization, we have:

6x^2 + 2x - 2.5 = 0

Expand 2x

6x^2 - 3x+5x  - 2.5 = 0

Factorize

3x(2x - 1)+2.5(2x  - 1) = 0

Factor out 2x - 1

(3x +2.5)(2x  - 1) = 0

Split:

(3x +2.5) = 0\ or\ (2x  - 1) = 0

In both cases, solve for x

3x = -2.5\ or\ 2x = 1

x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}

x = -0.8\ or\ x = 0.5 --- approximated
