Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form
Answer:
-5/3
Step-by-step explanation:
To solve for slope we use the slope formula which is y2-y1/x2-x1.
For this problem I chose the points: (-5,10) and (-2,5)
-5 is x1, 10 is y1, -2 is x2 and 5 is y2
We now plug in the points into the slope formula:
5-10/-2-(-5)= -5/3
You can say 4? Because the greatest common factor of 12 and 20 is 4
First you plug in the missing values
y=3 x=4 z=2
3÷2×4-2
than you solve
the answer is 4
