__________
5x^2 + 16x + 3 = 0
we are going to multiply 5 by 3 to get 15.
now which two numbers ( which give product 15) are added or subtracted to get 16 => 15 × 1
5x^2 + 15x + x + 3 = 0
5x ( x + 3 ) + 1 ( x + 3 ) =0
(5x + 1)(x + 3) = 0
5x + 1 = 0
•◆x = -1/5◆•
x + 3 = 0
•◆x= -3◆•
the two values which we get are -1/5 and -3.
