Answer:
1) x = -1 or x = -10 (either of them are both correct)
2) x = 3 or x = -5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2 + 11x + 10 =0
Step 1: Factor left side of equation.
(x + 1)(x + 10) = 0
Step 2: Set factors equal to 0.
x + 1 = 0 or x +10 = 0
x = −1 or x = −10
2x^2 + 4x − 30 = 0
x = 3 or x = −5
x^2 +x +1
See below for the tableau. The quotient is x^2 +x +1.
___
The remainder is 2.
Answer: Alberto caught up to Omar after 6 seconds, when Alberto had to run 54 meters.
2 * x = 2 * 3 = 6
9 * y = 9 * 2 = 18
18 + 6 = 24
x = 3
y = 2
487 ÷ 14
