Answer:
Step-by-step explanation:
-11x (5lx + 12)=(-11x)(51x)+(-11x)(12)
=-561x²-132x
Short answer : x = -13/3
But let's solve your equation step-by-step.
-2(x+8)=4x+10
Step 1: Simplify both sides of the equation.
(Distribute)
Step 2: Subtract 4x from both sides
Step 3: Add 16 to both sides.
Step 4: Divide both sides by -6.
Answer:
x = -13/3
The answer is $0.8
200/160=1.25
200+160=360/1.25/160=200.8
so the answer is $0.8
Answer:
2·x^3 + 5·x^2 - 8·x - 20 = 0
You see that the term will be 0 for x = 2
(2·x^3 + 5·x^2 - 8·x - 20) / (x - 2) = 2·x^2 + 9·x + 10 = 0
You can use the abc-formula to solve the quadratic equation.
x = -2.5 ∨ x = -2
So the factored form will be
2·x^3 + 5·x^2 - 8·x - 20 = 2·(x - 2)·(x + 2)·(x + 2.5)
