Question

Can someone help me with this pls

Answer 1

x = 1/3 or x = -2/3

Explanation:

Let's solve your equation step-by-step.

9x2+3x−2=0

For this equation: a=9, b=3, c=-2

9x2+3x+−2=0

Step 1: Use quadratic formula with a=9, b=3, c=-2.

`x=(-b\pm√(b^2-4ac) )/(2a)`

`x=(-(3)\pm√((3)^2-4(9)(-2)) )/(2(9))`

`x=(-3\pm√(81) )/(18)`

x = 1/3 or x = -2/3

Answer 2

`\huge\text{Hey there!}`

`\huge\textbf{What is the quadratic formula?}`

`\rm{x = (-b \pm √(b^2 - 4ac))/(2a)}`

`\textsf{Or even}`

`\rm{ax^2 + bx + c = 0}`

`\huge\textbf{What are we looking for?}`

`\rm{9x^2 + 3x - 2 = 0}`

`\huge\textbf{What are the labels in the equation?}`

`\mathsf{a \rightarrow 9}\\\\\mathsf{b\rightarrow 3}\\\\\mathsf{c \rightarrow -2}`

`\huge\textbf{Solving for your equation:}`

`\rm{x = (-(3)\pm √(3^2 - 4(9)(-2)))/(2a)}`

`\huge\textbf{Simplify it:}`

`\rm{x = (-3\pm √(81))/(18)}`

`\rm{x = (1)/(3)\ or\ x = - (2)/(3)}`

`\huge\textbf{Therefore, your answer should be:}`

`\huge\boxed{\frak{\mathsf{x} = (1)/(3)\ or\ \mathsf{x} = - (2)/(3)}}\huge\checkmark`
