The standard form of a quadratic equation is ,
ax² + bx + c = 0.
And the formula to find the discriminant is b² - 4ac.
Here the first step is to change the given equation into standard form. So, add 1 to each sides of the equation. Therefore,
2x² – 9x + 2+1 = –1 + 1
2x² – 9x + 3 = 0 
Next step is to compare the given equation with this equation to get the value of a, b and c.
After comparing the equations we will get a = 2, b = -9 and c = 3.
So, discriminant = b²- 4ac
=( -9)²-4 (2)(3)
= 81 - 24
= 57
So, discriminant of the given equation is 57.
57 is greater than 0 and square root of 57 will result real number.
So, the correct choice is C: The discriminant is greater than 0, so there are two real roots.
 
        
                    
             
        
        
        
Take 3/7 and multiply it by 2 to find out how much she knits in one hour. Then take that value and multiply by 12 to find out how much she knits in 12 hours.
3/7 x 2 = 6/7
6/7 x 12 = 72/7 or 10 2/7.

Answer:
43.3 cupcakes
Step-by-step explanation:
If shamans has 3&1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcakes can she make
From the above question
1/ 13 cup = 1 cup cake
3 1/3 cups = x
Cross Multiply
1 /13 × X = 3 1/3 × 1
x = 10/3 ÷ 1 /13
x = 10/3 × 13/1
x = 130/3
x = 43.333333333 cupcakes
