<span>the correct equation is
- 4j² + 3j - 28 =0
ax² + bx + c,
a = -4, b=3 c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
The answer there is no real roots</span>
I say B, I had to google it to make sure, but there are 3 phases in interphase. Interphase occurs before mitosis. The third phase in interphase is the DNA being copied.
Take 1/2 of b and squaer it so
(b/2)^2 would complete the square
(sign doesn't matter becaus when squareing, sign goes positive)
