The simplified form of given expression is 
<em><u>Solution:</u></em>
Given that we have to simplify the expression
<em><u>Given expression is:</u></em>

We can simplify the expression by multiplying each term in first bracket with each term term in second bracket


Simplify the above expression by multiplying the numbers in each term and adding the coefficients of like variables in each term

Combine the like terms


Thus the expression is simplified
Step-by-step explanation:
phytagora:
a^2+b^2=c^2
10^2+24^2=c^2
100+576=c^2
676=c^2
c=√676
c=√169×4
c=13×2
=26
Answer:
x =0 and x = 4
Step-by-step explanation:
It is a quadratic function and hence will have two roots. It cuts graph at 2 points( x - axis ). Hence has two roots.
If the problem is 3(15x - 17), none of those expressions are correct. You would multiple the 3 to each term (hence the "distributive" part) to get 45x - 51.
