Consider this expression:
[tex]\[ -4x^2 + 2x - 5(1 + x) \][/tex]

What expression is equivalent to the given expression?
[tex]\[ \square x^2 + \square x + \square \][/tex]


Sagot :

To simplify the given expression [tex]\(-4x^2 + 2x - 5(1 + x)\)[/tex], we need to follow these steps:

1. Distribute the [tex]\(-5\)[/tex] through the parentheses:
[tex]\[ -4x^2 + 2x - 5 \cdot 1 - 5 \cdot x \][/tex]

2. Simplify the terms:
[tex]\[ -4x^2 + 2x - 5 - 5x \][/tex]

3. Combine like terms:
- Combine [tex]\(2x\)[/tex] and [tex]\(-5x\)[/tex]:
[tex]\[ 2x - 5x = -3x \][/tex]
- Therefore, we get:
[tex]\[ -4x^2 - 3x - 5 \][/tex]

So, the equivalent expression is:
[tex]\[ \boxed{-4} x^2 + \boxed{-3} x + \boxed{-5} \][/tex]
