Answer:
the answer is b:-6
Step-by-step explanation:
hoped I helped:)
We divide when converting pints to quarts because pints are smaller units of measurements than quarts, so when converting pints to quarts, our answer will be getting smaller. This is because 2 pints= 1 quart, so since we are trying to find the amount of quarts that the pints can make up, we will always divide the pints by 2. (since 2 pints= 1 quart)
Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
x = [-7 ± √(49 - (-8) ) ] / ( -4 )
x = [-7 ± √(57) ] / ( -4)
x = [-7 ± sqrt(57) ] / ( -4 )
x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
