To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6
(x - 3)(x + 5)
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3

2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4
what is the solution of x-5y=10 and 2x-10y=20
-2y square exp power -2x-1
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
No, it equals -2xy. lrn2math
