Question

find roots of 2x2-8x+15\2 ?​

Answer 1

Answer:

x = 5/2 or 3/2

Step-by-step explanation:

given quadratic equation is $2x^2 - 8x + 15/2 = 0$

⇒ $2x^2 - 5x - 3x + 15/2 = 0$

⇒ $x(2x - 5) -3/2(2x - 5) = 0$

⇒$(2x - 5)(x - 3/2) = 0$

⇒ x = 5/2 or 3/2

Answer 2

Answer:

Here,

a=2

b=-8

c=15/2

Now,

x= ( - b ± ✓b^2 - 4ac)/2a

x=( 8± ✓ 64-60)/4

x=( 8±✓4)/4

x= (8 ± 2)/4

x=(8+2)/4 or (8-2)/4

x= 5/2. or. 3/2

So, the roots of 2x^2 - 8x+15/2 are 5/2 and 3/2..
