Question

Find the discriminant of x2 + 5x +5 ?

Answer 1

Step-by-step explanation:

discriminant =b²-4ac

where in the given equation we have a=1

b= 5

c=5

now substitute In the above formula

b²-4ac

(5)²-4(1)(5)

25- 20

5

Answer 2

$\mathfrak{\red{\underline{\underline{Question}}}}$

Find the discriminant of $x^{2} + 5x + 5$

$\mathfrak{\red{\underline{\underline{Answer}}}}$

$\boxed{5}$

$\mathfrak{\red{\underline{\underline{Step\: by\: step\: solution }}}}$

$x^{2} + 5x + 5$

Here,

a = 1

b = 5

c = 5

Discriminant (D) = ?

We know,

$\boxed{ D = b^{2} - 4ac}$

So,

$D = 5^{2} - 4(1)(5) \\ D = 25 - 20 \\ D = 5$
