Question

, using a suitable identify to get each of the following products (×+3) (×+5)​

Answer 1

Answer:

Step-by-step explanation:

(x+a)(x+b)=(x)2+x(a+b)+ab

(x+3)(x+5)= x2+x(3+5)+3(5)

               =x2+x(8)+15

               =x(8+2)+15

               =x(10+15)

               =x(25)

               =25x

Answer 2

$hey \: here \: is \: your \: answer$

$(x + 3) \: (x + 5)$

$by \: using \: formula \: of \: ......$

$(x + a) \: (x + b) = {x}^{2} + (a + b)x + a \times b$

$x = x \: and \: a = 3 \: and \: b = 5$

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

$(x + 3)(x + 5) = {x}^{2} + 8x + 15$

$hence \: verified \:$
