Answer:
x=0
Step-by-step explanation:
You can combine the equation to get 2sin(3/2 +x) = -2
divide both sides by 2 and you get the equation equal to -1. sin is equal to -1 when the value inside is 3/2 so this is the answer.
Answer:
(i) 5 + 2√6
(ii) 1 - 2√6
Step-by-step explanation:
(i) (√3+√2)(√3+√2)
⇒ √3(√3+√2) + √2(√3+√2)
or
⇒ (√3)² + (√3 × √2) + ( √2 ×√3 ) + ( √2 × √2 )
or
⇒ 3 + √6 + √6 + 2
or
⇒ 5 + 2√6
(ii) (√3+√2)(√3-√2)
⇒ √3(√3-√2) + √2(√3-√2)
or
⇒ ( √3 × √3 ) - ( √3 × √2) + ( √2 × √3 ) - ( √2 ×√2)
or
⇒ ( 3 ) - ( √6 ) + ( √6 ) - ( 2 )
or
⇒ 1 - 2√6
From the graph of a quadratic equation, you can find:
The roots. These are the points where the graph crosses the x-axis, and is the solution of the quadratic equation when y=0. Usually, there are either two or zero.
The coefficient of the leading term. In the quadratic equation y= ax^2 + bx + c,
the parabola points upward if a is positive, and downward if a is negative.
The vertex. You can find the vertex, or where the two sides of the parabola meet, by looking at the graph.
