Question

solve - 3x square + 5x + 12 =0 ​

Answer 1

Answer:

x = 4/3

or

x= ( -3 )

.............

Answer 2

Answer:

Given:

3x²+5x−12

The pair 9,4 works to split the middle term.

Use this pair to split the middle term, then factor by grouping:

3x²+5x-12=0

3x²+9x-4x−12=0

3x(x+3)-4(x+3)=0

(3x-4)(x+3)=0

Hence:

x= 4/3  or  x= -3
