2a2 - 13a + 15 = (2a - 3) (a - 5)

a2(2a2-21a+49) a2(2a-7)(a-7)

2a-5

3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)

2a2+3a2 = 5a2

8

2a+5

(a2 + a + a2) = (2a2 + a) = a (2a + 1)

If you mean 2a times a and a is a variable, the answer would be 2a2.

If I've read your question correctly, you need to subtract: a2 +2a -7 a2 -4a2 +5a2 -6 = 2a2 -6 Note, if x - y = z, then y = x - z; so: 2a2 -6 - (a2 -2a +1) = 2a2 -6 - a2 +2a -1 = a2 +2a -7

2a2

2a+6b

(2a - b)(2a + b)

2a

It is: 2(a-2)

2a2+33a+136 = (2a+17)(a+8) when factored

(2a+1)(a+1)

(a - 2b)(2a - b)

6a squared-8ab+2a factor completely and check mentally

2a + 11a - 5a = 8a
