Final answer:
To solve (7p+2)²=75, take the square root of both sides resulting in two potential solutions for p, which are (-2 + √75) / 7 and (-2 - √75) / 7.
Step-by-step explanation:
To solve the equation (7p+2)²=75 using the square root property, we first take the square root of both sides of the equation. This yields two possible solutions because the square root of a number can be either positive or negative. The steps are as follows:
- Take the square root of both sides of the equation, remembering to include both the positive and negative roots: √(7p+2)² = ±√75.
- Simplify the square root of the left side to get 7p+2 and simplify the right side to ±√75.
- To find the two solutions for p, subtract 2 from both sides of each equation and then divide by 7: p = (±√75 - 2) / 7.
Therefore, the solutions for p are (-2 + √75) / 7 and (-2 - √75) / 7.
