Question

Which of the following is correct about the following function?522 +232 + 12O The roots of the function are and -4The roots of the function are (52 - 4) (0 - 3)The factored form is (5z +2) (3 + 10)O The factored form is (5z +2) (3+6)2

Answer 1

Let's Lets say we are given a function

`5x^2+23x+12`

The roots of the function would be

`\begin{gathered} 5x^2+23x+12 \\ 5x^2+20x+3x+12 \\ 5x(x+4)+3(x+4)_{} \\ (x+4)(5x+3) \end{gathered}`
`\begin{gathered} x=-4 \\ x=-(3)/(5)=-0.6 \\ \end{gathered}`

The roots of the functions are -4 and -3/5

The factored form of the function would be (x+4)(5x+3)
