X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
Answer:
-13/20
Step-by-step explanation:
-4/5 x 4/4 = -16/20
3/20 x 1/1 = 3/20
-16/20 + 3/20 = (-16 + 3 = -13)
-13/20
4 goes into 20 5 times,
so you have 1/5 if you reduced it
1/5 is .20 or 20%
to check your work or for an easy way to do it, 1 divided by 5 or 4 divided by 20 which is also .20 or 20%
I hope this helps you
-14+?= -17
?= -17+14
?= -3
