solve by factoring : -2y(y+4)=0?

Answer 1

( -2 y ) ( y + 4 ) = 0
y = 0 , y = - 4

Answer 2

y = 0 and y = -4

Answer 3

This math expression is already factored. So, as simple as

- 2y = 0 then, y = 0

or y - 4 = 0

y = 4

Sorry is y + 4 = 0

So y = - 4

Answer 4

-2y=0 or y+4=0
y=0/(-2) or y=-4
=0
thankx for giving an oppturnity

Answer 5

-2y(y+4)=0
either 2y=0 or y+4=0
if 2y=0 then y=0/2=0
& if y+4=0 then y= - 4
so y=0 or - 4

Answer 6

EXPRESSION: 12x^2 + 19x - 4 = 0 to unravel by making use of factoring, in simple terms multiply the consistent, ie the huge type that would not have a variable related to it, as a effect ( - 4) to the coefficient of the squared variable, as a effect, 12. making use of this, we can locate the single huge type which would be used simply by fact the middle expression. 2 multiples could be subsituted for the single huge type and that they could sum the origion al center huge type. The origional center huge type is 19x, so the multiples of - 40 8 could sum to 19. we can confirm that those multiples are 3 and sixteen. the hot expression will become: 12x^2 + 3x + 16x - 4 = 0 we can simplify this new expression extra beneficial, by making use of factoring: to element, extract comparable words in the expression. right here we will team words each and every, with comparable hidden expressions. in the 12x^2 and 3x, a similar term to extract may well be 3x, for the reason that the two one in all them have multiples of three and x. In 16x - 4, a similar words right it is 4. this is often extracted and located infront of the bracket. 3x( 4x + a million) + 4(4x - a million) = 0 the two brackets could have a similar expression, consequently, the indicators could be replaced.

Answer 7

-2y(y+4)=0

You've got two things multiplied together here, -2y and y+4. Two things multiplied together are only zero when one of them is zero.

So either -2y = 0 (in which case y=0) or y+4=0 (in which case y=-4)

Answer 8

Y= -4.

Answer 9

-2y(y+4)=0
-2y^2+4y=0

Y=0 and Y=-4

Answer 10

- 2y(y + 4) = 0
- 2y = 0, y = 0
y + 4 = 0, y = - 4

Answer: (0, - 4)
