Is 8 the answer ?
just divide the given number by 3 . you will get the answer 8
This is a quadratic in the form of ax squared +bx +c
So
a = 3
b = -5
c = 2
Hope this helps!
Answer:
x= -15
Step-by-step explanation:
Divide to both sides by -5 to isolate the variable.
<u>-5x</u>=<u>75</u>
-5 -5
x= -15
This gives you the answer of x= -15.
I'll just factor the above equation.
x² + 18x + 80
x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10 Correct pair
(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80
x+8 = 0
x = -8
x+10 = 0
x = -10
x = -8
(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0
(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0
I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.
