Question

(y -6)(2y+7) solve find the product by vertical or horizontal

Answer 1

Answer:

$\large\boxed{2y^2-5y-42}$

Step-by-step explanation:

Given:

(y-6)(2y+7)

You can also solve with distributive property.

Use foil method formula.

$\large\boxed{\textnormal{FOIL METHOD FORMULA}}$

$\displaystyle (A+B)(C+D)=AC+AD+BC+BD$

$\large\boxed{\textnormal{DISTRIBUTIVE PROPERTY}}$

$\displaystyle A(B+C)=AB+AC$

Solutions:

A=y

B=(-6)

C=2y

D=7

$\displaystyle y*2y+y*7+(-6)* 2y+(-6)*7$

Change negative sign to positive sign.

$\displaystyle +(-x)=-x$

$\displaystyle 2yy+7y-6*2y-6*7$

Solve.

$\displaystyle 2yy+7y-6*2y-6*7=\boxed{2y^2-5y-42}$

$\large\boxed{2y^2-5y-42}$

So, the correct answer is 2y²-5y-42.
