Answer

Explanation:

Step1: Analyze current step

We have $3(x^{2}-10x + 25)-2 + 4x$. The next logical step is to distribute the 3.

Step2: Recall distribution rule

We use the distributive property $a(b + c+d)=ab+ac + ad$. Here $a = 3$, $b=x^{2}$, $c=-10x$, $d = 25$. $3(x^{2}-10x + 25)-2 + 4x=3x^{2}-30x+75 - 2+4x$

Answer:

Distribute the 3 to each term in the parentheses by multiplying.
