(x - 3)(x + 5)

To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6

2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9

2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9

No, it equals -2xy. lrn2math

(x - 3)(x + 5)

To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6

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

2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4

2x2 = 200 Divide both sides by 2: x2 = 100 Take square roots of both sides: x = -10 or x = +10

No, it equals -2xy. lrn2math
