(2r - 6)(-5r+4) what is the product
Akimi4 [234]

Answer:

-10r^{2} +38r-24

Step-by-step explanation:

Apply FOIL method: (a+b)(c+d)=ac+ad+bc+bd

a=2r,b=-6,c=-5r,d=4

=2r(5-r)+2r*4+(-6)(-5r)+(-6)*4

Apply minus - plus rules

+(-a)=-a,(-a)(-b)=ab

=-2*5rr+2*4r+6*5r-6*4

Simplify

Multiply -2*5rr=-10r^{2}

=-10r^{2} +2*4r+6*5r-6*4

Multiply 2*4r=8r

=-10r^{2} +8r+6*5r-6*4

Multiply 6*5r=30r

=-10r^{2} +8r+30r-6*4

Combine like terms

=-10r^{2} +38r-6*4

Multiply -6*4=-24

=-10r^{2} +38r-24

-10r^{2} +38r-24
