Find $a$ such that $ax^2+15x+4$ is the square of a binomial

Step-by-step explanation:

Step-by-step explanation:

We want to find such that:

two same numbers, , multiply to be and

add up to be 15.

We can solve the last equation by dividing both sides by 2:

So this means can be rewritten as:

Divide both sides by 4:

So .

Let's check:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
