Differentiate 3x^2-5x

weqwewe [10]

Answer:

6x - 5

Step-by-step explanation:

$Let \: y = 3 {x}^{2} - 5x \\ \\ \frac{dy}{dx} = \frac{d}{dx} (3 {x}^{2} - 5x) \\ \\ = 3 \frac{d}{dx} {x}^{2} - 5 \frac{d}{dx} x \\ \\ = 3(2x) - 5(1) \\ \\ \boxed{\boxed{\huge \purple{\frac{dy}{dx}} \pink{ = } \orange{6x - 5}}}$

.. Discuss the nature of the root of equation x2 + 2x + 3 = 0

Mariana [72]

Answer:

No real roots

Step-by-step explanation:

Given equation:

x² + 2x + 3 = 0

On comparing the equation by ax² + bx + x = 0, We get: a = 1, b = 2 and c = 3

To Find the nature of the roots of the equation firstly we need to find the discriminant of the equation. The expression b²- 4ac is called the discriminant.

$~$

Two Distinct real roots, if b² - 4ac > 0
Two equal real roots, if b² - 4ac = 0
No real roots, if b² - 4ac < 0

$\\ \: \: \dashrightarrow \: \: \: \sf {b}^{2} - 4ac = 0 \\ \\ \\\: \: \dashrightarrow \: \: \: \sf (2)² - 4 \times 1 \times 3 = 0 \\ \\ \\ \: \: \dashrightarrow \: \: \: \sf 4 - 4 \times 1 \times 3 = 0 \\ \\ \\ \: \: \dashrightarrow \: \: \: \sf 4 - 12 = 0 \\ \\ \\ \: \: \dashrightarrow \: \: \: \sf {\underline{\boxed{\sf{\purple{ -8 > 0}}}}} \\ \\$
