Answer:
140x^2−384x+37
Step-by-step explanation:
(10x+−1)(14x+−37)
=(10x)(14x)+(10x)(−37)+(−1)(14x)+(−1)(−37)
=140x^2−370x−14x+37
X=9
Pull out like factors :
-4x + 36 = -4 • (x - 9)
Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-9 = 0
Add 9 to both sides of the equation :
x = 9
