Question

√7y square-6y-13√7 factories​

Answer 1

Step-by-step explanation:

root7 y²-6y-13 root7

split the middle term

root7 y²-13y+7y-13 root7

y(root7-13)+root7(root7y-13)

factors (y+root7)&(root7y-13)

Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\sf\green{13 \sqrt{7} \times \sqrt{7} = 13 \times 7 = 97 } \\ \sf\pink{ { \sqrt{7}y }^{2} - 6y - 13 \sqrt{7} } \\ \sf\pink{ = > { \sqrt{7}y }^{2} - (13y - 7y) - 13 \sqrt{7} } \\ \sf\pink{ = > { \sqrt{7}y }^{2} - 13y +7y - 13 \sqrt{7} } \\ \sf\pink{ = > y( \sqrt{7}y - 13 ) + \sqrt{7}( \sqrt{7}y - 13 ) } \\ \sf\pink{ = > (y + \sqrt{7} )( \sqrt{7} y - 13)} \\ \sf\pink{} \\ \sf\purple{y = \sqrt{ - 7} \: ,\: \frac{13}{ \sqrt{7} } } \\ \large\boxed{ \fcolorbox{blue}{yellow}{hope \: it \: help \: you}}$
