Log_(10)(x² - 4x + 7) = 2
Take the base 10 anti log of both sides.
x² - 4x + 7 = 10² = 100
x²- 4x - 93 = 0
Quadratic Formula
x = [4 ± √(4²-4(1)(-93))]/[2(1)] = [4 ± 2√97)]/2 = 2 ± √97
To factor an expression, you need to find the GCF or Greatest Common Factor of all of the pieces of the expression.
The greatest common factor of 5x and -10 is 5. So, when we factor this, we divide both pieces of the expression by 5.
Your final answer is 5(x-2)
What Do you need help with if you added a picture we cant see it
Answer:
63+38=101
Step-by-step explanation:
For this one you can use 3/8 + 3/8 since 3+3 is equals to 6 and the 8 stays as it is.
I hope this helps.
YOU'RE WELCOME :D
