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
Answer:
x = −1 or x = −10
2x^2 + 4x − 30 = 0
Answer:
x = 3 or x = −5
I think the answer is A but I could be wrong
She is correct
because ↓
2 -5(x) - 14 = 0
-12 - 5(x)
-5(x) - 12
-5(x) = 12
Then, we get the value of "x" which is 2.4
