4(2 - x)(2 + x)

Step-by-step explanation:

16 - 4x² ← factor out 4 from each term

Solve each system by elimination.<br> −5x − 10y = 15<br> −3x + 10y = 25
yaroslaw [1]

Answer:

\boxed{x = -5~~and~~ y =1}

Step-by-step explanation:

-5x - 10y = 15

<u>-3x + 10y = 25 </u>+

-8x = 40

x = \frac{40}{-8}

x = -5

.

Substitute the value of x to one of equations

-5(-5) - 10y = 15

25 - 10y = 15

-10y = 15 - 25

-10y = -10

y = \frac{-10}{-10}

y = 1

Using the quadratic formula to solve 5x=6x squared -3, what are the values of x?
kiruha [24]
Answer: 5+sqrt(97)/12, 5-sqrt(97)/12 or we write it as [5+/-sqrt(97)]/(12)

5x=6x^2-3

6x^2-5x-3=0

x=-b+/-sqrt(b^2-4ac)/2a

x=-(-5)+/-sqrt((-5^2-4(6)(-3))/2(6)

x= 5+/-sqrt(97)/12

And decimal form is;

x=1.237, -0.4041

If anyone has any questions please feel free to ask and I’ll reply ASAP. Thanks
