Question

Use the Quadratic formula to find the solution of the following equation
2x^2+3x=2​

Answer 1

x=--2 and x=1/2

Explanation:

this is the answer in simple form

Answer 2

x1 = -2; x2 =
`(1)/(5)` or 0.5

Explanation:

`2x^(2)+3x=2`

`2x^(2) +3x-2=0`

`D=b^(2) -4ac`

`D=3^(2)-4*2*(-2)`

`D=9+16=25=5^(2)`

`x=(-b+-√(D) )/(2a)`

`x=(-3+5)/(2*2) =(2)/(4) =(1)/(2) = 0.5`

`x=(-3-5)/(2*2)=-(8)/(4) =-2`

x1 = -2; x2 =
`(1)/(5)` or 0.5
