Question

6x2 - x - 2 = 0
solve by factorisation method​

Answer 1

Answer:

62−−2=0

62−−2=0

6x^{2}-x-2=06x2−x−2=0

=6

a={\color{#c92786}{6}}a=6

=−1

b={\color{#e8710a}{-1}}b=−1

=−2

c={\color{#129eaf}{-2}}c=−2

=−(−1)±(−1)2−4⋅6(−2)√2⋅6

x=\frac{-({\color{#e8710a}{-1}}) \pm \sqrt{({\color{#e8710a}{-1}})^{2}-4 \cdot {\color{#c92786}{6}}({\color{#129eaf}{-2}})}}{2 \cdot {\color{#c92786}{6}}}x=2⋅6−(−1)±(−1)2−4⋅6(−2)

2

=−±2−4√2

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 quadratic formula.
