Question

x² - 5x + 5 find value of the polynomial​

Answer 1

Answer:

TO SOLVE THIS QUESTION WE APPLY QUADRANT FORMULA:

$\frac{ - b \sqrt[ + - ]{ {b}^{2} - 4ac} }{2a}$

HERE b=-5

a=1

c=5

PUT VALUE IN FORMULA

$\frac{ - ( - 5) \sqrt[ + - ]{ {( - 5)}^{2} - 4 \times 1 \times 5 } }{2 \times 1}$

$\frac{5 \sqrt[ + - ]{25 - 20} }{2}$

$\frac{5 \sqrt[ + - ]{5} }{2}$

$\frac{5 + \sqrt{5} }{2} and \: \frac{5 - \sqrt{5} }{2}$

THEY ARE ROOT.OF EQUATION❤
