Factor of 15(X2 +2xy) |
|
Answer» ong>Answer: Step-by-step explanation: Start by factoring 15x2+2xy−24y2 and then HOPE for the best. FACTOR this by decomposition or by magic.
Note that 15×24=360 . So we seek two NUMBERS with product being 360 and difference 2 with the larger assigned a positive sign. The numbers are 20 and 18 . So continue in the following way:
15x2+2xy−24y2=15x2+20xy−18xy−24y2=5x(3x+4y)−6y(3x+4y)=(5x−6y)((3x+4y).
Now for the hoping part. The −6 could mess the whole THING up. In fact, had it been some other number, the quadratic would not factor. Here’s what we do. SET y=0 and factor the result. The factored form is (5x+3)(3x−2) with the important numbers being 3 and −2 . This suggests that
15x2+2xy−24y2−x+24y−6=(5x−6y+3)(3x+4y−2) .

Sin theta + cos theta is equal to cosec theta prove LHS and RHS equal |
|
Answer» ong>ANSWER: We have to prove that cot+cosecθ sinθ =2+ cotθ−cosecθ sinθ or, cotθ+cosecθ sinθ − cotθ−cosecθ sinθ =2
Now,
⇒ LHS = cotθ+cosecθ sinθ − cotθ−cosecθ sinθ
⇒ LHS = cosecθ+cotθ sinθ + cosecθ−cotθ sinθ
⇒ LHS = sinθ{ cosecθ+cotθ 1 + cosecθ−cotθ 1 }
⇒ LHS = $$sin \, \theta\left\{\dfrac{cosec \, \theta \, - \, cot \, \theta \, + \, cosec \, \theta \, + \, cot \, \theta}{cosec^2 \, \theta \, - \, cot^ \, \theta}\right\} \, = \, sin \, \theta \, \left(\dfrac{2 \, cosec \, \theta}{1} \right)$$
⇒ LHS = sinθ(2cosecθ)=2sinθ× sinθ 1 =2=RHS
⇒ LHS = 2 = RHS
ALTERNANATIVELY,
LHS = cotθ+cosecθ sinθ
⇒LHS=sinθ(cosecθ−cotθ) [∵ cosecθ+cotθ 1 =cosecθ−cotθ]
⇒ LHS = sinθ( sinθ 1 − sinθ cosθ )=sinθ( sinθ 1−cosθ )
⇒ LHS = 1 - COS θ
⇒ = 2 - (1 + cos θ)
⇒ LHS = 2 - 1−cosθ (1+cosθ)(1−cosθ)
⇒ LHS = 2 - 1−cosθ (1−cos 2 θ)
⇒ LHS = 2 - 1−cosθ sin 2 θ =2− sinθ 1−cosθ
sinθ =2− sinθ 1 − sinθ cosθ
sinθ
⇒ LHS = 2 - cosecθ−cotθ sinθ = RHS Hope it help's you Drop some Thanks Mark as Brainliest |
