What are the solutions of 3x2 + 14x + 16 = 0?

x = , –2
x = –2,
x = , 2
x = , 2

option (A) is correct.

x = -2

Step-by-step explanation:

Given : equation

We have to solve for x,

Consider the given equation

we will solve the given quadratic equation using middle term split method, we have,

14x can be writen as 6x + 8x , we have,

Taking 3x common from frst two terms and 8 common from lasttwo term , we have,

Taking (x + 2) common, we have,

Thus, Apply zero product rule,

or

or

Thus, option (A) is correct.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
