Question

-3x^2+7x-4=0 solve the given quadratic equation by factorization method​

Answer 1

Answer:

Notice that if you invert the sign of the term of odd degree then the sum of the coefficients is zero. That is:

3

−

7

+

4

=

0

We can deduce that

x

=

−

1

is a root and

(

x

+

1

)

a factor:

0

=

3

x

2

+

7

x

+

4

=

(

x

+

1

)

(

3

x

+

4

)

So the other root is

x

=

−

4
