Using the identity ( x+a) 9x+b) = x2 + (a+b)x +ab, find the following product: (4p+3q)(4p+7q)

Aleks [24]

Answer:

$(4p+3q)(4p+7q)=x^2+40pq+21q^2$

Step-by-step explanation:

$Given\ (x+a)(x+b)=x^2+(a+b)x+ab\ ...............................(1)\\\\We\ have\ to \find\ (4p+3q)(4p+7q)\\\\Compare\ (4p+3q)(4p+7q)\ with\ (x+a)(x+b)\\\\x=4p\\\\a=3q\\\\b=7q\\\\Substitute\ these\ values\ in\ eq(1)\\\\(4p+3q)(4p+7q)=x^2+(3q+7q)\times 4p+3q\times 7q\\\\(4p+3q)(4p+7q)=x^2+10q\times 4p+21q^2\\\\(4p+3q)(4p+7q)=x^2+40pq+21q^2$

I need to solve for p and have a rationalized denominator

Travka [436]

Answer:

$p = \pm \dfrac{\sqrt{r(st - 1)}}{st - 1}$

or

$p = \dfrac{\sqrt{r(st - 1)}}{st - 1}$

Step-by-step explanation:

$t = \dfrac{p^2 + r}{p^2s}$

$p^2st = p^2 + r$

$p^2st - p^2 = r$

$p^2(st - 1) = r$

$p^2 = \dfrac{r}{st - 1}$

$p = \pm \sqrt{\dfrac{r}{st - 1}}$

Your picture cuts out the assumption. If the assumption is that all variables are non-negative, then the answer is

$p = \sqrt{\dfrac{r}{st - 1}}$

$p = \dfrac{\sqrt{r}}{\sqrt{st - 1}}}$

$p = \dfrac{\sqrt{r}}{\sqrt{st - 1}}} \times \dfrac{\sqrt{st - 1}}{\sqrt{st - 1}}$

$p = \dfrac{\sqrt{r} \sqrt{st - 1}}{\sqrt{st - 1}\sqrt{st - 1}}$

$p = \dfrac{\sqrt{r(st - 1)}}{st - 1}$
