= (3x + 5)(x + 1) so x = -5/3 or -1
x - 3
8x + 5 = 25(- 5 from both sides)8x = 20(divide both sides by 8)x = 2.5
x2 + 8x - 5 = 0 ∴ x2 + 8x + 16 = 21 ∴ (x + 4)2 = 21 ∴ x + 4 = ± √21 ∴ x = -4 ± √21
Given f(x) = 8x + 5 So f(8) = 8 * 8 - 5 = 64 - 5 = 59
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
5 + 8(3 + x) 5 + 24 + 8x 29 + 8x
8x + 3 = 50 8x = 47x = 47/8x= 5 and 7/8ths
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x
x² + 8x + 15 = (x + 5)(x + 3)
8x plus 4y equals 5 is 8x + 4y = 5.
(x+5)(x+3) = x^2 +8x+15
It is: 29+8x
(x+5)(x+3)
x = -8
