Question

2.x² - 11x + 5 = 0 find x​

Answer 1

Answer:

x=5 and x=1/2

Step-by-step explanation:

2x²-11x+5=0

x= -b±√b²-4ac/2a

a=2 b=-11 c=5

after substituting and solving we get

x=5 and x=1/2

Answer 2

Answer:

$\frac{11+ \sqrt101 }{2}$ , $\frac{11- \sqrt101 }{2}$

Step-by-step explanation:

x² - 11x + 5 = 0

x = [-b ± √(b²-4ac) ] / 2a

=> x =  [-(-11) ± √((-11)²-4(1)(5)) ] / 2(1)

       = [11± √(121-20) ] / 2

       = [11± √101 ] / 2

       = $\frac{11+ \sqrt101 }{2}$ , $\frac{11- \sqrt101 }{2}$
