Answer:
C)x = +/-15
Step-by-step explanation:
15x15=225
-15x-15=225
Answer:
I think it is triangle, pentagon, heptagon, decagon
6x^2+14x+4
First factor out all numerical factors (=2 in this case)
2(3x^2+7x+2)
look for m,n such that m*n=3*2, m+n=7 => m=6, n=1
2(3x^2+6x + 1x+2)
Factor 3x^2+6x into 3x(x+2)
2( 3x(x+2)+1(x+2) )
factor out common factor (x+2)
2(x+2)(3x+1)
=>
6x^2+14x+4=2(x+2)(3x+1)
{(3,0),(6,1),(9,2)} because
when you plug in the values you get
3-3=3(0) = 0=0
6-3=3(1) = 3=3
9-3=3(2) = 6=6
