Question

The roots of quadratic equation 5xᒾ -4x +5=0 are:​

Answer 1

Step-by-step explanation:

GIVEN:-

• 5xᒾ -4x -5=0

SOLUTION:-

$5 {x}^{2} - 5x + 1x - 5 = 0$

$5(x - 5)1(x - 5) = 0$

$(x - 5)( x + 1) = 0$

$x = - 1$

$x = 5$

Answer 2

answer X=2+-√39/5

5x^-4x+5=0

the roots of the quadratic equation

ax^+bx+c=0 are given by

x=-b+-√b^-4ac/2a

for the given equation 5x^-4x+5=0,

b^-4ac=(-4)^-4(5)(-7)=16+140=156

so ,the roots are

x=4+-√156/2(5)

x=4+-2√39/10

x=2+-√39/5
