Question

what is the product of (x + 3) (x + 5)?

Answer 1

(x-3)(x-5)

x2-15-3x+5x

x2+5x-3x-15

x(x+5)-3(x+5)

x=3 or -5

Answer 2

Given: The equation is$(x + 3) (x + 5)$.

We have to find the product of the above equation.

By using the multiplication property, we are solving the above equation

• As we know that the multiplication is a method to get the product by multiplying two or more values.
• Multiplication is denoted by the symbol(x).

There are six properties of multiplication is given below:-

• Closure property of multiplication
• Commutative property of multiplication
• Associative property of multiplication
• Distributive property of multiplication over addition
• Identity property of multiplication
• Zero property of multiplication

We are solving in the following way:

We have,

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

Hence, the product of the above equation will be$x^{2} +8x+15$.
