Name the binomial you can multiply by (x + 9) to get the product x2 + 5x - 36?
4 - x, x + 6, x - 4,x - 6
Solution:
Given: Quadratic equation is x2 + 5x - 36
By splitting the middle term
= x2 + 9x - 4x - 36
Taking out the common terms
= x(x + 9) - 4(x + 9)
= (x + 9)(x - 4)
(x + 9) is the given polynomial
Consider the other binomial as z
(x + 9)× z = x2 + 5x - 36
It can be written as
z = (x2 + 5x - 36)/(x + 9)
z = [(x + 9)(x - 4)]/(x + 9)
z = x - 4
Therefore, (x - 4) is the other binomial.
Name the binomial you can multiply by (x + 9) to get the product x2 + 5x - 36?
Summary:
The binomial you can multiply by (x + 9) to get the product x2 + 5x - 36 is (x - 4).
