Absolute Value
1. The problem is to solve the equation $2|x + 4| = 40$.
2. Start by isolating the absolute value expression:
Notable Identities
1. The problem is to identify which of the given functions correspond to the first or second notable identities:
$$\alpha^2 + 2\alpha b + b^2 = (a + b)^2$$
Absolute Value Equation
1. **State the problem:** Solve the equation $$\frac{3}{2} |x - 5| = 0$$.
2. **Isolate the absolute value:** Since $$\frac{3}{2}$$ is a nonzero constant, divide both sides by $$\fr
Fraction Operations
1. Problem: Calculate $\frac{3}{4} + \frac{5}{8}$.
- Convert $\frac{3}{4}$ to eighths: $\frac{3}{4} = \frac{6}{8}$.
Quadratic Solutions
1. The problem is to find the number of solutions to the quadratic equation $$-\frac{3}{7}x^2 + x - 7 = 0$$.
2. To determine the number of solutions, we calculate the discriminant
Geometric Sequence
1. The problem is to find the next three numbers in the sequence: 4, 8, 16, 32, _, _, _.
2. Observe the pattern: each number is multiplied by 2 to get the next number.
Simplify Radicals
1. **State the problem:** Simplify the expression $$(2\sqrt{x} + \sqrt{y}) - (\sqrt{x} - 2\sqrt{y})$$.
2. **Remove parentheses carefully:**
Simplify Square Root
1. **State the problem:** Simplify the expression $$\sqrt{\frac{25x^6y^3}{16x^2y^9}}$$ and interpret the result.
