anonymous · Answer

is the answer 1 number or is it a pair?

anonymous · Answer

as i see it the answer is 
b2 − 4ac 
and its value from the equation is 7^2-4*2*3 =25

anonymous · Answer

what do you mean the value of the equalization?

anonymous · Answer

equation

anonymous · Answer

that part of the question Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation: 
2x2 + 7x + 3 = 0

the quadaratic function is written as f(x)= ax^2+bx+c
so  i choosed b2-4ac and from your equation a=2,b=7 and c=3
so b2-4ac is equal to 25

ok thanks

anonymous · Answer

if you want to know more about that term (b2-4ac) it is called the Discriminant you can see its page on Wikipedia
