The GCF is 4a. The equation factors into 4a(5a + 9)
5 is the greatest common factor of 15 and 305.15 factors to [3 5]305 factors to [5 61]common factors are [5] ■5A:5
Factor 5a-15 Factor out the 5; 5(a-3)
5a
The GCF of 35 a^2 and 85ab is 5a. The GCF of 35 and 85 is 5, and the GCF of a squared and ab is a.
15a + 12 = 3(5a + 4)
2a + 3a = 5a
The GCF is 5a.
5a times 5a would equal 25a^2.
The GCF is 4a. The equation factors into 4a(5a + 9)
5a = a + a + a + a + a
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
(5a)2 = 25a2
