Use the quadratic formula to solve x2 + 9x + 10 = 0.<br> What are the solutions to the equation?

vampirchik [111]

Answer:

$\large\boxed{x=\dfrac{-9\pm\sqrt{41}}{2}}$

Step-by-step explanation:

$\text{The quadratic formula of}$

$ax^2+bx+c=0$

$\text{If}\ b^2-4a0,\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\=========================================$

$\text{We have}\ x^2+9x+10=0\\\\a=1,\ b=9,\ c=10\\\\\text{substitute:}\\\\b^2-4ac=9^2-4(1)(10)=81-40=41>0\qquad _{\text{two solutions}}\\\\\sqrt{b^2-4ac}=\sqrt{41}\\\\x=\dfrac{-9\pm\sqrt{41}}{2(1)}=\dfrac{-9\pm\sqrt{41}}{2}$

Whatas the answer to 12.6+4m=9.6+8m

SVEN [57.7K]

Answer:

$\large\boxed{m=\dfrac{3}{4}=0.75}$

Step-by-step explanation:

$12.6+4m=9.6+8m\qquad\text{subtract 12.6 from both sides}\\\\12.6-12.6+4m=9.6-12.6+8m\\\\4m=-3+8m\qquad\text{subtract}\ 8m\ \text{from both sides}\\\\4m-8m=-3+8m-8m\\\\-4m=-3\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4m}{-4}=\dfrac{-3}{-4}\\\\m=\dfrac{3}{4}=0.75$
