Hello!
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
Multiply by the numbers.
Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.
First, apply used their FOIL.
Foil: (a+b)(c+d)=ac+ad+bc+bd
2x*7x+2x(-6z)+5z*7x+5z(-6z)
Then you can also apply by the minus/plus sign.
2*7xx-2*6xz+5*7xz-5*6zz
And finally simplify by equation.
2*7xx-2*6xz+5*7xz-5*6zz
Answer: =14x²+23xz-30z²
Hope this helps!
