Question

Show that x=-2 is a solution of 3x^2+13x+14=0

Answer 1

Answer:

x=-2

p(x)=3x²+13x+14

p(-2)=3(-2)²+13(-2)+14

=3(4)-26+14

=12-26+14

=26-26

=0

So x=-2 is a solution

Answer 2

Answer:

$\huge\boxed{\purple{hello}}\boxed{\pink{dude}}$

Given that g(x)= -2

Step-by-step explanation:

p(x)=3x²+13x+14

p(-2)=3(-2)²+13(-2)+14

p(-2)=12-26+14

p(-2)=26-26

p(-2)= 0

So,it proves that 0 is the ANSWER if g(x) is-2
