Question

How do you expand \[3(x + 5)?\]

Answer 1

Hint:
For solving such types of questions you must use basic rules (formulas). With the help of the basic formula of expansion we will solve this question in a very easy way.

Formula used:
$a(x + y) = (a \times x) + (a \times y)$

Complete step by step solution:
For solving such type of question we will use formula which is given below,
$a(x + y) = (a \times x) + (a \times y)$
Now, for this question value of a is $3$
For this question value of x is $x$
For this question value of y is $5$
So here, after substituting a, x and y values in formula we get,
$3(x + 5) = (3 \times x) + (3 \times 5)$
$ = 3x + 15$
So using this method we can expand such an equation.

Therefore, answer of this question is $3(x + 5) = 3x + 15$

Note:
For solving such types of questions you have to read and understand the question after that find formula or rule which helps us to find the answer. And after that step by step do calculation. Always try to use simple methods. Do not always remember the answer or full method just try to understand.
