Answer: 
Step-by-step explanation:
We have the following polynomial:
This is a polynomial of the form 
. Following this rule to expand it, we have:
Applying common factor 
:
Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:
60
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
Answer:
g(t) - h(t) = -2t - 1
Step-by-step explanation:
g(t) - h(t) = t-3-3t+2
= -2t -1
10 ft i think. 5/9 of 180 (which is 12 x 15) is 100 and 10 x 10 is 100
Answer:
a/b = c/d --> d = b*c/a
d is the forth proportional
a) d = 2*3/1 = 6
b) d = 3*4/0.5 = 24
c) d = b*5/a = 5*b/a
