(a)
(x+2)² - 4 - 7
= (x+2)² - 11
a = 2
b = -11
(b)
(x+2)² - 11
→
(x+2)² = 11
→
x1 = -2 + √11 = 1.3166
x2 = -2 - √11 = -5.3166
(x+2)² - 4 - 7
= (x+2)² - 11
a = 2
b = -11
(b)
(x+2)² - 11
→
(x+2)² = 11
→
x1 = -2 + √11 = 1.3166
x2 = -2 - √11 = -5.3166

This type of question will lead to Graph Sketching, which is super popular. So, must know how to get to the first answer. The entire question with sketching, can go up to 4-5 marks. Very Expensive. So keep practicing. You can do it, lily;)
