(x+3)(2x-6)=26
2x(to the second power)-18=26
2x(to the second power) -18-26=26-26
2x(to the second power)-44 = 0
x=square root of 22,x= negative square root of 22
decimal form : x = 4.69042,x= -4.69042
Answer:
hi I was wondering if I could come in
Rearrange 0.16x^2+4.8xy+36y^2
Take 4 out 4(0.04x^2+1.2xy+9y^2)
Now its a square 4(0.2x+3y)^2
If we multiply it out
0.04x^2+0.6xy+0.6xy+9y^2
0.04x^2+1.2xy+9y^2
