5x2 + 15x = 0
5x(x + 3) = 0
therefore, x = 0 or x + 3 = 0
that is, x = 0 or x = -3
5x(x+3)
10
X= (3/5 , -2)
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
6 + 10 = 16
5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
5(x2 - 3x - 6)
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
The GCF is 5x2
The discriminant is 385.
