Question

solve 2 x square - 5 x + 3 is equals to zero by using formula quadratic equation​

Answer 1

Answer:

1.5 , 1

Step-by-step explanation:

2 x square - 5 x + 3 is equals to zero

2 x² - 5 x + 3 = 0

 x² - (5/2) x + 3/2 = 0

x = 5/2 ±√(25/4 - 6 ÷ 2 = 5/2 ±√1/4÷ 2 = 5/2 ± 1/2÷ 2 = (5 ± 1 ) ÷ 4

x = 1.5 , 1

Given :-

2x² - 5x + 3 = 0

====================

To Find :-

Zeroes of quadratic polynomial

===================

Solution :-

We know that,

Discriminant method = b² - 4ac

Here, b is -5, a is 2 and c is 3

____________[Put Values]

→ D = (-5)² - 4(2)(3)

→ D = 25 - 24

→ D = 1

Now, we have to find roots. So,

We know that

x = (-b ± √D)/2a

x = -(-5) ± √1 / 2(2)

x = (5 ± √1)/4

Hence, zeroes can be

x = (5 + √1) / 4

Or

x = (5 - √1) / 4
