How do i factor -7x^2+5x+12

yKpoI14uk [10]

Answer:

-(x + 1)(7x - 12)

Step-by-step explanation:

Step 1: Factor out a -1

-1(7x² - 5x - 12)

Step 2:

Think. Answer this question: "What 2 numbers multiply up to -12 and adds up to -5 while 7 is an x coefficient?". You answer should be -12 and 1.

So, <em>factor</em>.

-1(x + 1)(7x - 12)

To double check, just expand/FOIL everything and see if it is the same as the original expression.

Answer:

$\bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}$

Step-by-step explanation:

$\bold{S=2\pi r^2+2\pi rh}\\\\\bold{2\pi r^2+2\pi rh\ =\ S}\\\\{}\qquad -2\pi r^2\quad\ \ -2\pi r^2\\\\{}\quad \bold{2\pi rh\ =\ S-2\pi r^2}\\\\\div(2\pi r)\quad\ \div(2\pi r)\\\\\bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}$
