Mathematics
1 answer:
Thepotemich [5.8K]1 year ago
7 0

Answer:

(x-1)(x+4)

Step-by-step explanation:

Given:

x^2+3x-4

The best way to write a polynomial with three terms as a product of binomials is to FACTOR!

The middle number is 3 and the last number is -4.

Factoring means we want something like

(x+?)(x+?)

We need two numbers that...

ADD together to get 3 and

MULTIPLY together to get -4

Test the numbers -1 and 4:

-1+4=3\\(-1)4=-4

These are the right numbers! Now, I can write them as factored binomials!

(x-1)(x+4)

What is the value of x in the equation 2x+3y=36y when y=6?
jonny [76]

Answer:

y = 6 so

2x + 3y = 36y is equal to:

2x + 3*6 = 36*6

-> 2x + 18 = 216

We must now move 18 to the other side of the equation. As we do that, we also change it's sign to negative 18:

2x = 216 - 18

We simplify this

2x = 198

Now, that we got to this point, we know that 2x is equal to 198. To find x we must divide the both sides of the equation by two:

2x/2 = 198/2

And we get that

x = 99
