Question

2) solve the following quadratic equations using
formula méthod.
6x²+x-2=0​

Answer 1

Answer:

6x

2

−x−2=0

6x

2

−4x+3x−2=0

2x(3x−2)+(3x−2)1=0

(2x+1)(3x−2)=0

2x+1 = 0 or 3x-2 = 0

x = -1/2 , x=2/3.

Answer 2

Use the quadratic formula

=

−

±

2

−

4

√

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac

Once in standard form, identify a, b and c from the original equation and plug them into the q
