Question

factorization 15+ a²b + 5b+ 3a²​

Answer 1

Step-by-step explanation:

• 15+a^2b+5b+3a^2
• 15+5b+3a^2+a^2b
• 5(3+b)+a^2(3+b)
• (5+a^2)(3+b)

Answer 2

Answer

$(3 + b) \times (5 + a^{2} )$

Step-by-step explanation:

$15 + a {}^{2}b + b + 3a ^{2} \\ \\ \\5(3 + b) + a ^{2} b + 3a ^{2} \\ \\ \\ \\ 5(3 + b) + a ^{2} \times (b + 3) \\ \\ \\ \\ \\ (3 + b) \times (5a ^{2}$
