Question

2x - 5х + 1(х+3)(x-1)​

Answer 1

$2x - 5x + 1 = - 3x + 1$

$(x + 3)(x - 1) = {x}^{2} - x + 3x - 3 = {x}^{2} + 2x - 3$

Answer 2

To simplify the expression 2x - 5x + 1(x+3)(x-1), we can follow the order of operations (PEMDAS/BODMAS) and simplify it step by step:

1. Distribute the 1(x+3)(x-1) term: 1(x+3)(x-1) = (x+3)(x-1) = x(x-1) + 3(x-1) = x^2 - x + 3x - 3 = x^2 + 2x - 3

Now the expression becomes: 2x - 5x + x^2 + 2x - 3

2. Combine like terms: -5x + 2x = -3x 2x + 2x = 4x

The expression simplifies to: -3x + x^2 + 4x - 3

The final simplified form is: x^2 + x - 3
