Question

find the discriminant of the following quadratic equations. 1). 3x^2+5x+2=0​

Answer 1

Answer:

heya mate ☺

➡ Given,

$3x ^{2} + 5x + 2 = 0$

➡ Here a = 3 , b = 5 and c = 2

So, formula for discriminate :

$b ^{2} - 4ac \\ = (5) ^{2} - 4 \times 3 \times 2 \\ = 25 - 24 \\ = 1$

✌ hope it helps u ✌

Answer 2

$\huge\underline\mathbb{\red S\pink{O}\purple{L} \blue{UT} \orange{I}\green{ON :}}$

★ Given that

Find the discrimination for 3x² + 5x + 2 = 0

★ Let,

• a = 3
• b = 5
• c = 2

$\tt\: ★ By\:using\:discrimination(∆) \:formula :$

$\tt\purple\:⟹\:b^{2}-4ac$

• Substitute the values.

$\tt\:⟹ {(5)}^{2} - 4(3)(2)$

$\tt\:⟹25 - 24$

$\tt\:⟹1$

$\underline{\boxed{\bf{\purple{∴ ∆ > 0, 2 \: real \: roots.}}}}$
