As spring has sprung, Thomas decides to over seed his lawn. After 3 weeks of spreading grass there are 5,250 blades of grass. After 7 weeks there are 5,952 blades of grass. Write an equation to represent this situation.

In Michigan, mid-August through September is the ideal time to repair or seed a new lawn, but if the weather is favorable, it may be possible to seed into early October and still achieve good establishment. It is riskier to start in October because you never know what the weather is going to do. If it stays warm through the month, newly seeded grass will have some time to become established. If it gets cold too soon, the seed may germinate, but the plants may not have enough time to become established.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
