The two expressions below are equivalent. Find the values of a and b that make them equivalent. The two expressions are:
5x^2+bx-12
(5x+a)(x-4)

Step-by-step explanation:

We are given that:

First, we can distribute the right-hand side:

Distribute:

Rewrite:

Since it is equivalent to the above expression, the coefficients of the variables must match. This means that:

Solving for a in the second equation gives:

Therefore:

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
