X^2+2x+1 is a perfect square trinomial True of False?

Nimfa-mama [501]

Answer:

True.

Step-by-step explanation:

It is because it is in the form $a^2x^2+2abx+b^2$ and this equals $(ax+b)^2$ .

Why it is in that form: well comparing $a^2x^2+2abx+b^2$ , we have $a=1, b=1$ . Testing, plug in those values:

$(1)^2x^2+2(1)(1)x+(1)^2$

$1x^2+2x+1$

$x^2+2x+1$ .

This has the squared form of $(x+1)^2$ .

Test if you like:

$(x+1)^2$

$(x+1)(x+1)$

Use foil to expand:

First: x(x)=x^2

Outer: x(1)=x

Inner: 1(x)=x

Last: 1(1)=1

---------------Add together

$x^2+2x+1$

It does indeed equal.

2[3x-(4x-6)]=5(x-6) Solve and answer the linear equation.

OleMash [197]

Answer: x = 6

Step-by-step explanation:

2[3x - (4x - 6)] = 5(x - 6)

2[3x - 4x + 6] = 5x - 30

2[-x + 6] = 5x - 30

-2x + 12 = 5x - 30

+2x +2x

12 = 7x - 30

+30 +30

42 = 7x

$\frac{42}{7} = \frac{7x}{7}$
