Trinomial 2x² + 4x + 4.
It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c
(in our case Δ = 4² - (4)(2)(4) → Δ = - 32
We know that: x' = -1 + i and x" = -1 - i
If Δ > 0 we have 2 rational solutions x' and x"
If Δ = 0 we have1 rational solution x' = x"
If Δ < 0 we have 2 complex solutions x' and x", that are conjugate
In our example we have Δ = - 16 then <0 so we have 2 complex solutions
That are x'= [-b+√Δ]/2.a and x" = [-b-√Δ]/2.a
x' =
2x+10=40
2x=30
30 divided by 2
X=15
1. false because they have the same slope and y-intercept so they have infinite number of solutions
2. true
5.8 you divide 5 to both side then cross the 5 on the left side out because it cancel out after divide 29 and 5 and. Get 5.8
A negative exponent for powers of 10 represent numbers between 0 and 1.
