Question

find the factors of this polynomial 7a²+14a.
1. 7(a+2)
2. 7a(a+14)
3. 7a(a+2)
4. 14(a+2). please give me answer ​

Answer 1

$\red{ The \: factors \: of \: given \: polynomial }\\\red{ 7a^{2} + 14a } \\= (7a) \times a + (7a) \times 2 \\= \blue{ 7a ( a + 2 ) }$

Therefore.,

$\red{ The \: factors \: of \: given \: polynomial }\\\red{ 7a^{2} + 14a }\green { = 7a ( a + 2 ) }$

$Option \: \pink{ ( 3 ) } \: is \: correct .$

Answer 2

Answer:

= 7a ( a + 2 )

Step-by-step explanation:

7a² + 14a

= 7 × a × a + 7 × a × 2

= 7a × a + 7a × 2

= 7a ( a + 2 )
