Answer:
1 2 real
2. No real
3. 2 Real
4. One real Multiplicity 2.
Step-by-step explanation:
Find the value of the discriminant D (b^2 - 4ac) :-
1 . D = (1)^1 -4 * -3 * 12 = 1 + 144 = 145
D is positive so there re 2 real solutions.
2. D = (-6)^2 - 4*2*5 = 36 - 40 = -4
D is negative so there are NO real solutions.
3. D = (7)^2 - 4 * 1 * -11 = 49 + 44 = 93
2 real
solutions
4. D = (-8)^2 - 4* -1 * -16 = 64 - 64
1 solution. Multiplicity 2.
bearing in mind that 5¼ is just 5.25 converted to decimal.
let's say the number is "x", thus "x" is the 100%.
12.6 is 5.25%, what is the 100%? namely "x"?
