Question 2

Answer:

20x² -15x - 10 = 190 that the anwer

Question 3

$\text{Hey there!}$

$\mathsf{Quadratic\ formula: 20x^2-15x-10=0}$

$\mathsf}The\ formula\ is: ax^2}\mathsf{+bx+c=0}$

$\mathsf{ax^2=20x^2}$

$\mathsf{bx=-15x}$

$\mathsf{c=-10}$

$\mathsf{0=0}$

$\mathsf{x=(-b\pm√(b^2-4ac))/(2a)}$

$\mathsf{Plug\ in\ our\ values!}$

$\mathsf{x=(-(-15)\pm√(-15)^2-4(20)(-10)))/(2)(20))}$

$\mathsf{Double\ negatives=postive}$

$\mathsf{x=\pm(15√(1025))/(40)}$

$\mathsf{Solve\ above\uparrow\ and\ you\ have\ your\ answer!}$

$\boxed{\mathsf{\mathsf{Thus,\ the\ answer\ is: x=(3)/(8)+(1)/(8)√(41)\ or \ x=(3)/(8)+(-1)/(8)√(41)}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
