Complete the expressions that would make them a perfect square trinomial.

kirza4 [7]

Answer:

a) 16

b) 100

c) 64

d) $\frac{81}{4}$ [/tex]

Step-by-step explanation:

Perfect square trinomial:

A perfect square trinomial has the following format:

$(x \pm a)^2 = x^2 \pm 2ax + a^2$

x² – 8x

$x^2 - 8x = x^2 - 2ax$

So 2a = 8, a = 4. Then

$a^2 = 4^2 = 16$

The perfect square trinomial is $x^2 - 8x + 16$

b. x2 + 20x +

2a = 20, so a = 10

$a^2 = 10^2 = 100$

The perfect square trinomial is $x^2 + 20x + 100$

x² – 16x +

2a = -16, so a = -8.

$a^2 = (-8)^2 = 64$

The perfect square trinomial is $x^2 - 16x + 64$

d. x2 + 9x +

$2a = 9$ , so $a = \frac{9}{2}$

$a^2 = (\frac{9}{2})^2 = \frac{81}{4}$

The perfect square trinomial is $x^2 + 9x + \frac{81}{4}$ [/tex]

How would I solve 5(x -2) =2x +16?

Alborosie

Answer: First, multiply 5 by x-2 to get 5x-10. We now have 5x-10=2x+16. Subtract 2x on both sides: 3x-10=16. Add 10 to both sides: 3x=26. Lastly, divide by 3x to isolate x: x=8.6666667
