Question

Which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring?

−b b2 − 4ac 2a

Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

can anyone answer this ???

Answer 1

\[b ^{2}-4ac\]

Answer 2

the general quadratic equation is \[ax ^{2}+bx+c=0\]
here a=2
b=7
c=3

Answer 3

if
\[b^2-4ac=0\ \text{or a perfect square}\]
then the quadratic can be solved by factorisation

Answer 4
