Question

find the product of (3a2b+4a) and ( ab+a2) and verify the result for a = 2 and b = 1​

Answer 1

Step-by-step explanation:

$(3 {a}^{2}b + 4a)(ab + {a}^{2} )$

${3a}^{2}b(ab + {a}^{2} ) + 4a(ab + {a}^{2} )$

$3 {a}^{3} {b}^{2} + {3a}^{4}b + 4 {a}^{2}b + {4a}^{3}$

$\mathfrak{put \: the \: following \: valu e \:in \: given \: equation }$

${3(2)}^{3} {1}^{2} + {3(2)}^{4} \times 1 + {4(2)}^{2} \times 1 + {4(2)}^{3}$

$= 28 + 48 + 16 + 32$

$= 44 + 48 + 32$

$= 92 + 32$

$= 124 \: is \: the \: answer$
