Write the polynomial in standard form. 7+5x+2x^2 use the lower case x as your variable, use ^ to show exponents and do not use any spaces. for example: 2x^5+3x^3-x^2

answer: you need the equation in the question so i can answer it

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: the answer is 84.

step-by-step explanation: i just answered it and 84 is correct. look at the graph and it should be the number between 2 points on the graph.
