Answer:
d) 7xy(-6y + 1)
e) -13x
Step-by-step explanation:
Simplify:
d) -42xy² + 7xy
-42xy² = 7 * (-6) * x * y²
7xy = 7 * x * y
HCF = 7xy
Take the common term 7xy from (-42xy² + 7xy)
-42xy² + 7xy = 7xy * (-6y) + 7xy * 1
= 7xy*(-6y + 1)
e)
[tex]\sf \dfrac{-45x^2}{3x}+\dfrac{14x^2}{7x}=\dfrac{3*(-15)*x*x}{3*x}+\dfrac{7*2*x*x}{7*x}\\\\\\[/tex]
= -15x + 2x
= -13x
