Answer:

one real solution

Step-by-step explanation:

We can use the discriminant to find the types of solutions

b^2 -4ac  where    ax^2 +bx+c=0

Since

x^2 -8x+16 =0

we know a=1 b=-8 and c=16

(-8)^2 - 4(1)(16)

64 -64 = 0

If the discriminant > 0 we have two real solutions

If the discriminant = 0 we have 1 real solutions

If the discriminant < 0 we have two complex solutions

Since it equals zero, we have one real solution

Answer:

One real solution because the answer is (x-4)^{2}

Step-by-step explanation:

x^{2} -8x+16=\\(x-4)(x-4)

What are the real solutions to the equation 5x² + 29x + 20 = 0?
Readme [11.4K]

Answer:

x = -5,\: -\frac{4}{5}

Step-by-step explanation:

  • 5x^2 +29x + 20=0

  • \implies  5x^2 +25x +4x+ 20=0

  • \implies  5x(x +5) +4(x+ 5)=0

  • \implies  (x +5) (5x+ 4)=0

  • \implies  (x +5) = 0,\:(5x+ 4)=0

  • \implies  x = -5,\:x=-\frac{4}{5}

  • \implies  x = -5,\: -\frac{4}{5}

What is the answer? To this question
lianna [129]

Answer:

x = 5

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other.

Therefore,

4x - 5 = 3x

4x  = 3x + 5

4x - 3x = 5

x = 5

please help. i’ve been stuck on this question the past 10 minutes i’ve tried multiple times and still don’t get it. i need help
Softa [21]

Answer:

To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.

x +7 - 7 = -2 - 7

When you simplify further,

x = -9.

Hope this helps! :)
