Factor the equation y = x2 + 4x - 21.

pav-90 [236]

The factored form of given equation y = x^2 + 4x - 21 is (x + 7)(x – 3)

<u>Solution:</u>

Given, equation is $y=x^{2}+4 x-21$

We have to factor the above equation

Now, take the expression $\mathrm{x}^{2}+4 \mathrm{x}-21$

$\rightarrow x^{2}+4 x-21$

"4x" can be splitted as (7 - 3)x

$\rightarrow x^{2}+(7-3) x-21$

"21" can rewritten as $7 \times 3$

$\rightarrow x^{2}+7 x-3 x-7 \times 3$

Taking "x" as common from first two terms and "3" as common from next two terms

$\rightarrow x(x+7)-3(x+7)$

Taking "x + 7" as common term,

$\rightarrow(x+7)(x-3)$

Hence, the factored form of given equation is y = ( x + 7 )( x – 3 )

Write the product as a sum: 14cos(39x)sin(19x)

charle [14.2K]

Recall that

sin(<em>a</em> + <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) + cos(<em>a</em>) sin(<em>b</em>)

sin(<em>a</em> - <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) - cos(<em>a</em>) sin(<em>b</em>)

Adding these together gives

sin(<em>a</em> + <em>b</em>) + sin(<em>a</em> - <em>b</em>) = 2 sin(<em>a</em>) cos(<em>b</em>)

To get 14 cos(39<em>x</em>) sin(19<em>x</em>) on the right side, multiply both sides by 7 and replace <em>a</em> = 19<em>x</em> and <em>b</em> = 39<em>x</em> :

7 (sin(19<em>x</em> + 39<em>x</em>) + sin(19<em>x</em> - 39<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) + sin(-20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) - sin(20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)
