Question

(3x+2)(3x+5) pls multiply and use a property

Answer 1

Answer:

(x+a)(x+b)=x2+(a+b)x + ab

==> (3x)2 + (2+5)3x +2 ×5

==> 9x2+21x+10

Answer 2

Step-by-step explanation:

$(3x + 2)(3x + 5)$

Property:

$(x + a)(x + b) = {x}^{2} + (a + b)x + ab$

Therefore,

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

$= 9 {x}^{2} + 3 \times 7x + 10$

$= 9 {x}^{2} + 21x + 10$
