<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>
6-3=3
2/8-5/8=3/8
you would have to change the denominator
150 / 12 = 11.6666666667
11.6666666667 x 30 = approximately 350g of flour for 30 cakes
0.078, 0.5, 0.507, 0.75.
Hope it helps ; )
