If you take the common term 4a out of the expression 16a4 + 4a3, you get 4a(4a3 + a2), making it apparent that if you divide by 4a, the quotient is (4a3 + a2).
4a3 - 4a2 = 4a2*(a - 1)
5a-20 = -15
5a- 2a = 3
5a-20=
If you take the common term 4a out of the expression 16a4 + 4a3, you get 4a(4a3 + a2), making it apparent that if you divide by 4a, the quotient is (4a3 + a2).
a(4a^2 - 11)
4a3 - 4a2 = 4a2*(a - 1)
The GCF is 5a.
5a = a + a + a + a + a
4
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
(5a)^2 or a^2+10a+25
5a or 4a squared
30-5a = 25
It is: 5a2
6b-5a = 1
