Question

factories x^2 + 7√5x + 50

Answer 1

hi friend
x square +7√5x+50
x
${x }^{2} + 7 \sqrt{5} x + 50 \\ = {x}^{2} + 5 \sqrt{5} x + 2 \sqrt{5} x + 50 \\ = x(x + 5 \sqrt{5} ) + 2 \sqrt{5} (x + 5 \sqrt{5} ) \\ (x + 5 \sqrt{5} )(x + 2 \sqrt{5} )$

Answer 2

(X is equal to minus B plus minus root B square minus 4 AC )/ 2A

in this question A is equal to 1 , b is equal to 7 root 5 and C is equal to 50

put these values in the formula

we get X is equal to minus 1 plus minus square root of (7 root 5)^2 minus 4*1*50 divided by 2*1

by solving this you will get the answer....
