For fractions if the denominator is the same you go to the numerator (the top number) to compare. The bigger the numerator is (like 6) the higher it should go on your list.

If one of the roots of the quadratice quation x2+kx-12=0is4,what is the value of k?

uysha [10]

<h3>Given Equation:</h3>

$\huge \purple {\rm { {x}^{2} + kx - 12 = 0}}$

<h3>Value:</h3>

$\huge \purple {\rm {x = 4}}$

$\huge \purple {\rm {The \: value \: of \: k.}}$

<h3>Solution:</h3>

$\huge \purple {\rm { {(4)}^{2} + k(4) - 12 = 0}}$

$\huge \purple {\rm {or, \: 16 + 4 k - 12 = 0}}$

$\huge \purple {\rm {or, \: 4k = - 4}}$

$\huge \purple {\rm {or, \: k = \frac{ - 4}{4} = - 1}}$

<h2>Answer:</h2>

$\huge \purple {\sf {The \: value \: of \: k \: is \: -1}}$
