Question

(x+4)(x^2+2x-3) помогите пожалуйста)

Answer 1

х+4=0     или    х^2+2x-3=0
х=-4                 D=4-4(-3)=16=4^2
                         x1= -2+4/2 = 1
                         x2= -2-4/2 =-4

Answer 2

Factoring the Expression (x+4)(x^2+2x-3)

To factor the given expression (x+4)(x^2+2x-3), we can use the distributive property to expand the expression and then simplify it by factoring.

Expanding the expression: (x+4)(x^2+2x-3) = x(x^2+2x-3) + 4(x^2+2x-3)

Now, let's factor each part separately.

1. Factoring x(x^2+2x-3): - The expression x^2+2x-3 can be factored into (x+3)(x-1). - Therefore, x(x^2+2x-3) = x(x+3)(x-1).

2. Factoring 4(x^2+2x-3): - The expression x^2+2x-3 can be factored into (x+3)(x-1). - Therefore, 4(x^2+2x-3) = 4(x+3)(x-1).

Combining the results: (x+4)(x^2+2x-3) = x(x+3)(x-1) + 4(x+3)(x-1)

Now, we can factor out the common factor (x+3)(x-1): (x+4)(x^2+2x-3) = (x+3)(x-1)(x + 4 + 4x)

So, the factored form of the expression (x+4)(x^2+2x-3) is (x+3)(x-1)(x+4x+4).

This is the factored form of the given expression.
