-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
x2 + 6x = 7 ⇒ x2 + 6x + 9 = 7 + 9 ⇒ (x + 3)2 = 16 ⇒ x + 3 = ±4 ⇒ x = -7 or 1
√(6x) - 3 - 3√x = 1 √(6x) -3√x = 4 √x = 4/(√6 - 3) = -4(√6 + 3)/3 = 16/9*(15+6√6) = 16/3*(5+2√6) = 52.8, approx.
-22
root (6x - 2) = 4 therefore 6x - 2 = 16 therefore 6x = 16 + 2 therefore x = 3
-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.
If the square root of 6x-2=4 than we can square both sides and we have 6x-2=16 or 6x=18 and the solution set is the set that contains the number 3.
y=6x-16 y=-2x+8
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
-16 = 6x Swap: 6x = -16 Divide both sides by 6: x = -16/6 = -8/3 or -22/3 or -2.66...
x2 + 6x = 7 ⇒ x2 + 6x + 9 = 7 + 9 ⇒ (x + 3)2 = 16 ⇒ x + 3 = ±4 ⇒ x = -7 or 1
The solution of -6x = -16 is x = 2 2/3, which is greater than -16.
√(6x) - 3 - 3√x = 1 √(6x) -3√x = 4 √x = 4/(√6 - 3) = -4(√6 + 3)/3 = 16/9*(15+6√6) = 16/3*(5+2√6) = 52.8, approx.
6x-14x+16=27+11 answer: 4
6x - 2 = 16 : 6x = 16 + 2 = 18 : x = 18÷ 6 = 3 :x - 3 = 3 - 3 = 0 : x - 3 = 0
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
