The answer to this is b- 8
<span>i think you mean discriminant in part A
</span>
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
Answer:
f(-2) = -4
Step-by-step explanation:
f(x) = x^3-2x,
Let x = -2
f(-2) = (-2)^3 - 2(-2)
= -8 +4
= -4
48.5 is the answer.
Reason- an expression is an equation without an equal sign and this expression is saying 53.5 - 5.
