Question

discriminant of quadratic equation minus 4 m square - 4 x + 5 is equals to zero​

Answer 1

Answer:

Discrimination = -64

Step-by-step explanation:

Discrimination = b^2 - 4ac

a = 4

b = -4

c = 5

Discriminant = (-4)^2 - 4(4)(5) = 16 - 80 = -64

Given Equation,

$- 4 {x}^{2} - 4x + 5 = 0$

Here ,

a = - 4

b = - 4

c = 5

We know that ,

$D = {b}^{2} - 4ac \\ \\ D = {( - 4)}^{2} - 4 \times ( - 4) \times 5 \\ \\ D = 16 + 80 \\ \\ D = 96$

${\purple{\boxed{\large{\bold{Discriminant = 96 }}}}}$
