Question

solve by factoring:
2x^2-13x+20=0

Answer 1

2x^2 -8x -5x +20
2x(x-4)-5(x-4)
(2x-5)(x-4)
x= 4 or x= 5/2

Answer 2

(2x-5)(x-4)

Answer 3

where did you get the 8x and 5x from?

Answer 4

factor by grouping: what two numbers multiply to (a*c) or (2*20=40) and add to (b) or (-13)? -8 and -5
ax^2+bx+c

Answer 5
