Question

*The roots of equation 2x² - 5x + 3 = 0 are:*

1️⃣ -1 , -3/2
2️⃣ 1 , -3/2
3️⃣ 3/2 , 1
4️⃣ 3/2 , -1​

Answer 1

Step-by-step explanation:

2x^-5x+3=0

2x^-3x-2x+3=0

x(2x-3)-1(2x-3)=0

(2x-3) (x-1)=0

either(2x-3)=0 or(x-1)=0

2x-3=0,x-1=0

x=3/2,x=1

option 3 is right

Answer 2

Answer:

Compaire with ax²+bx+c=0

therefore a=2,b=-5,c=3=0

b²-4ac= (-5)²-4×2×3

=25-24

=1

x= -b±√b²-4ac/2a

x=-(-5)±√1/2×2

x=5±1/4

x=5+1/4 or 5-1/4

x=6/4 or 4/4

x=3/2 or 1

Option 3️⃣3/2,1. is right
