Answer:
Step-by-step explanation:
10 x = x - 3 Subtract x from both sides
10x - x = - 3 Combine like terms on the left
9x = - 3 Divide both sides by 9
9x/9 = -3/9
x = - 1/3 or x = - 0.333333
Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
