Question

2(x+5)²=???????????

Answer 1

2(х^2+10х+25)=0
2х^2+20х+50=0
2х^2+20х=-50
2х^2=-2,5
х^2=-1,25

Answer 2

2*(x^2 +2*5*x+5^2) =2*(x^2+10x+25)=2x^2+20x+50

Answer 3

To expand the expression 2(x + 5)², you'll follow these steps:

Step 1: Square the expression (x + 5) by multiplying it by itself. Step 2: Multiply the squared expression by 2.

Let's go through it step by step:

Step 1: Square the expression (x + 5) (x + 5)² = (x + 5) * (x + 5) = x * x + 5 * x + 5 * x + 5 * 5 = x² + 10x + 25

Step 2: Multiply the squared expression by 2 2(x + 5)² = 2(x² + 10x + 25)

So, 2(x + 5)² is equal to 2(x² + 10x + 25).
