Answer:

20x² -15x - 10 = 190 that the anwer

Answer 2

$\text{Hey there!}$

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

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

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

$\mathsf{bx=-15x}$

$\mathsf{c=-10}$

$\mathsf{0=0}$

$\mathsf{x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}}$

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

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

$\mathsf{Double\ negatives=postive}$

$\mathsf{x=\pm\dfrac{15\sqrt{1025}}{40}}$

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

$\boxed{\mathsf{\mathsf{Thus,\ the\ answer\ is: x=\dfrac{3}{8}+\dfrac{1}{8}\sqrt{41}\ or \ x=\dfrac{3}{8}+\dfrac{-1}{8}\sqrt{41}}}}}\checkmark$

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