Question

Pleas help me!!

Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.
-b b^2-4ac 2a
Use the part of the quadratic formula that you above and find its value, given the following quadratic equation:
4x^2 + 6x + 2 =0

Answer 1

1) Answer: The part of the quadratic formula tells us whether the quadratic equation can be solved by factoring is b^2-4ac

2) 4x^2+6x+2=0
ax^2+bx+c=0; a=4, b=6, c=2
b^2-4ac=(6)^2-4(4)(2)=36-32
b^2-4ac=4

Answer: b^2-4ac=4
