question 2
simplify the following expression
2x(-5 + 9)

Explanation:

Step1: Apply distributive property

We use the distributive property \(a(b + c)=ab+ac\), here \(a = 2x\), \(b=- 5\), \(c = 9\). So we have \(2x\times(-5)+2x\times9\)

Step2: Calculate each term

Calculate \(2x\times(-5)=-10x\) and \(2x\times9 = 18x\)

Step3: Combine like terms

Combine \(-10x\) and \(18x\), we get \(-10x + 18x=8x\)

Answer:

\(8x\)
