Luda [366]3 years ago
3 0

Answer:

A quadratic equation

Step-by-step explanation:

f(x) = (x + 3)(x - 7) \\ f(x) =  {x}^{2}  - 7x + 3x - 21 \\ f(x) =  {x}^{2}  - 4x - 21

-70y^2+90x^3+100yx^2-63xy<br>factor by grouping
Alexeev081 [22]
The idea of grouping is to get the terms in groups that allow you to factor out from each group something that becomes a factor in itself, leaving two factors behind that are alike. Like this: rearrange those terms so they are in this order:
(-70y^2 - 63xy) + (90x^3 + 100yx^2).  Now out of the first set we are going to factor out a -7y, and out of the second set we are going to factor out a 10x^2. When we do this, this is what we get: -7y(10y + 9x) + 10x^2(9x + 10y). As you can see, what's inside both sets of parenthesis is the same, just in a different order. We can factor that out now, leaving (9x + 10y)(10x^2 - 7y). And that is factored by grouping.

Write the equation of the line that passes through the points (3,5) and (-1,1). Put
dangina [55]

Given:

A line passes through the two points (3,5) and (-1,1).

To find:

The equation of the line in fully reduced point-slope form.

Solution:

If a line passes through two points, then the point slope form of the line is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is

y-5=\dfrac{1-5}{-1-3}(x-3)

y-5=\dfrac{-4}{-4}(x-3)

y-5=1(x-3)

Therefore, the  point slope form of the line in fully reduced form is y-5=1(x-3), here 1 is the slope of the line.
