10a * (a + 2)
Factor completely and check mentally 10a^2+20a
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
To determine the factors of the terms in the expression (20a + 15ab + 24b), we can factor each term. The factors of (20a) are (4 \times 5 \times a), the factors of (15ab) are (3 \times 5 \times a \times b), and the factors of (24b) are (3 \times 8 \times b). Common factors among the terms include (3) and (b). Thus, any statements indicating these common factors or the individual factors of each term would be true.

20a^2
Factor completely and check mentally 10a^2+20a
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a

5(4a + 7)
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
It is 20a - 5b - 9.
As written, that equals 32a - 8, which factors to 8(4a - 1) If you meant 20a^2 + 12a - 8, that factors to 4(5a - 2)(a + 1)

20a + 45 = 5(4a + 9)
To determine the factors of the terms in the expression (20a + 15ab + 24b), we can factor each term. The factors of (20a) are (4 \times 5 \times a), the factors of (15ab) are (3 \times 5 \times a \times b), and the factors of (24b) are (3 \times 8 \times b). Common factors among the terms include (3) and (b). Thus, any statements indicating these common factors or the individual factors of each term would be true.
-4(5a-3) = -20a + 12
