Answer:
(2p+9)^2
Step-by-step explanation:
We know this is a perfect square trinomial
a^2 +2ab +b^2 = (a+b)^2
a = 2p b = 9
a^2 = 4p^2
2ab = 2*2p*9 = 36p
b^2 = 81
Check
4p^2 +36p+81 = (2p+9)^2
I can't make out what the radius of the sphere is, but the equation you're looking for is:
For example:
If the radius of a sphere is 5 m, it's volume would be,
7x, 4y, 1are the terms, and 7x is the leading term.
Answer:
The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions
