2.n^2-13n+ 40
3. x^2-8x-20
5. x^2 + 7xy - 44y^2
6. 2x^2 + 7x +6

Answer 1

are u looking for the factors?

Answer 2

no just to work the problem out i already have the answer

Answer 3

1.1*99=99
11*9=99
11+9=20
2.1*40=40
-8*-5=40
-8+(-5)=-13
3.1*-20=-20
-10+2=-8
-10*2=-20
4.1*-44=-44
11-4=7
11*-4=-44
5.2*6=12
4+3=7
4*3=12

Answer 14

x^2+7xy-44y^2
=x^2+(11-4)xy-44y^2
=x^2+11xy-4xy-44y^2
=x(x+11y)-4y(x+11y)
=(x+11y)(x-4y)
