its 10
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
X= (3/5 , -2)
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.

-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5
x2 • (5x2 + x + 8)
5x2-8x-4
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
5x2-2x = 0 x(5x-2) = 0 Therefore: x = 0 or x = 2/5
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
