Solve by using square root: 4(x-1)^2+2=10

Scilla [17]

$4(x-1)^2+2=10\\\\4(x^2-2x+1)+2-10=0\\\\4 x^2-8x+4+2-10=0\\\\4 x^2-8x-4=0\ \ / :4\\\\x^2-2x-1=0\\\\x_{1}=\frac{-b-\sqrt{b^2-4ac}}{2a}=\frac{2-\sqrt{ (-2)^2-4*1*(-1)}}{2 }=\frac{2-\sqrt{ 8}}{2 }=\frac{2- \sqrt{ 4*2}}{2 }=\\\\=\frac{2-\sqrt{ 8}}{2 }=\frac{2(1- \sqrt{ 2})}{2 }=1- \sqrt{ 2}\\\\x_{2}=\frac{-b+\sqrt{b^2-4ac}}{2a}=\frac{2+\sqrt{ (-2)^2-4*1*(-1)}}{2 }=\frac{2(1+ \sqrt{ 2})}{2 }=1+ \sqrt{ 2}$

$Answer:\ x=1- \sqrt{2}\ \ or\ \ x= 1+ \sqrt{ 2}$

Ben is baking a cake. His recipe calls for 3/4 cups of sugar and 1/3 teaspoons of butter. How much sugar does Ben need per teasp

Alika [10]

Answer:

Improper fraction is 9/4 cups, Mixed number is 2 1/4 cups

9/4 cups of sugar or 2 1/4 cups of sugar

Step-by-step explanation:

36 tsp are in 3/4 of a cup

so you have 1/3 : 36

1/3 is less than a whole teaspoon, so the amount of sugar would be greater than 3/4 cups

1/4 cups of sugar: 1 tsp of butter; or 108 teaspoons of sugar: 1 teaspoon of butter

Hope this helps!
