-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
2 radical 30
1rad5 + 2rad5 = 3rad5 3 radical 5
radical 3 or 6
-3+-2=-5. In word form: negative three plus negative two equals negative five.
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
√3 + √3 = 2√3
2 radical 30
First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1
1rad5 + 2rad5 = 3rad5 3 radical 5
radical 3 or 6
-3+-2=-5. In word form: negative three plus negative two equals negative five.
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
3root(6)+5root(2) you really answered it yourself!
Negative 3 + one is negative 2.
first the two numbers have the same radicand which is radical 2 so we just add the numbers before them to become 7 radical 2
negative 5
