Question

Find the zeroes of the polynomial
4x square + 12x + 9.
plz give this with proper steps.​

Answer 1

Answer:

the zeroes of the polynomial are ,-3x/2  ,  -3x/2

Step-by-step explanation:

Given the polynomial $4x^{2} + 12x +9$

by splitting the middle term we get,

$4x^{2} + 6x + 6x + 9$

by taking common terms we get,

$2x(2x+3) + 3(2x + 3)$

which is

$(2x+3)(2x+3)$

lets equate it to 0

2x+3 = 0

2x = -3

x= -3/2

NOTE: it will repeat the same for another 2x+3 as it is also a zero

hence this is the solution of your problem
