That doesn't factor neatly. Applying the quadratic formula, we find two real solutions:
-1 plus or minus the square root of 11
x = 2.31662479
x = -4.31662479
(x-5)(x+3)
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 -4 = 10 -2x = 14 -x = 14/2 -x = 7 x = -7 easy.
(x-5)(x+3)
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
(x - 3)(x + 5)
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
2x - 5 = 15 2x = 20 x = 10
-2x -4 = 10 -2x = 14 -x = 14/2 -x = 7 x = -7 easy.
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
