Subtract 2+ 3a2 -12ab +4b2 from 1+ 8a2+16ab +2b2

Anvisha [2.4K]

The answer of the following subtraction is 5 $a^{2} -2b^{2} +28ab$

Step-by-step explanation:

As per the question the equation will be

$(1+8a^{2}+16ab+2b^{2} ) - (2+3a^{2} -12ab+4b^{2} )$

To find the subtraction,

The steps are as follow

= $1+8a^{2} +16ab+2b^{2} - 2 -3a^{2} +12ab-4b^{2}$

=1-2 + $8a^{2} -3a^{2} +2b^{2} -4b^{2} +16ab+12ab$

[ we took the variables with same power together]

=5 $a^{2} -2b^{2} +28ab$

Hope it helps you.

Using the law of sines, find the solutions for the missing inputs.

SashulF [63]

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) }$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\frac{12}{ \sin(38) } = \frac{a}{ \sin(57) }$
$180 - (85 + 38) = 57$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\sin(85) \times \frac{12}{ \sin(38) } = b$
$\sin(57) \times \frac{12}{ \sin(38) } = a$
sorry for the order of steps
