Question

*5m² - m = 0 for this quadratic equation find the value of discriminant.* 1️⃣ 1 2️⃣ 25 3️⃣ 5 4️⃣ 0​

Answer 1

Hey

Here is your answer,

5m^2 -m=0

b^2 - 4ac =0

(-1)^2-4x5x0=0

1=0

it has 1 as its discriminant

It has real roots.

Hope it helps you!

Answer 2

Answer:

Given :-

• 5m² - m = 0

To Find :-

• What is the value of discriminant.

Solution :-

Given Equation :

$\mapsto \bf 5m^2 - m =\: 0$

By comparing with ax² + bx + c = 0 we get,

where,

❒ a = 5

❒ b = - 1

❒ c = 0

According to the question by using the formula we get,

$\implies \sf\bold{\purple{Discriminant =\: b^2 - 4ac}}$

$\implies \sf Discriminant =\: (- 1)^2 - 4(5)(0)$

$\implies \sf Discriminant =\: \{- 1 \times (- 1)\} - 4 \times 5 \times 0$

$\implies \sf Discriminant =\: 1 - 4 \times 0$

$\implies \sf Discriminant =\: 1 - 0$

$\implies \sf\bold{\red{Discriminant =\: 1}}$

Hence, the roots are real and unequal roots.

$\therefore$ The discriminant of the given equation is 1 .

Hence, the correct options is option no (1) 1 .
