(4,4) is the answer I think
Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.
Answer:
=4x^2−12x+9
Step-by-step explanation:
=(2x+−3)(2x+−3)
=(2x)(2x)+(2x)(−3)+(−3)(2x)+(−3)(−3)
=4x2−6x−6x+9
=4x2−12x+9
