Question

Solve x2 + 4x − 12 = 0.

Answer 1

there are 4+ method to factor quadratic equation
for this question AC method (headphone) would easy

where you have to find `2` numbers when you `multiply` them you should get product of `AC` and when you `add` or subtract them you should get `middle` term

Answer 2

\[\huge\rm Ax^2+Bx+C=0\]
a=leading coefficient
b=middle term
c= constant term
what is a and c in that eqaution ?

Answer 3

equation*

Answer 4

x and -12 i think

Answer 5

nice
leading coefficient is one \[\rm 1x^2+4x-12\]
so what two number you should multiply to get -12 but when you add them you should get 4

Answer 6

am not sure

Answer 7

1 times -12 = -12 right
but 1-12 =-11 but we need 4 now what other number you can multiply to get -12 ?

Answer 8

is it 2 and -6

Answer 9

2 should be negative
cus we need POSITIVE 4
-2 times 6 =-12
6-2=4

Answer 10

so factors are (x + number )(x+number)

Answer 11

so the answer is -2 and -6

Answer 12

no.

Answer 13

not negative 6

Answer 14

wait do you have to solve for x or find factors ?

Answer 15

x

Answer 16

so i was right

Answer 17

no.
factors are (x+ first number)(x+2nd number)
set it equal to zero
remember one of them is negativve

Answer 18

(x+6)(x+(-2))
now solve for x

Answer 19

x+(-2)= 0
x= ?
