Question 622656
The correct factors are (3x-7)(6x-5)
She had (6x-7)(3x-5)
when multiplying by foil, (6x-7)(3x-5) equals:
18x*2 - 30x - 21x + 35 which equals:
18x^2 - 51x + 35
when multiplying by foil, (3x-7)(6x-5) equal:
18x^2 - 15x - 42x + 35 which equals:
18x^2 - 57x + 35
She got the coefficients right (3x and 6x) and she got the constants right (7 and 5), but she put them in the wrong places.
factors she used were:
(3x-7)(6x-5)
correct use of the factors was:
(6x-7)(3x-5)
