(x + 10)(x + 4)
(x + 10)(x + 4)
You didn't bother to list the binomials to choose from, but the two binomial factors of x2 + 6x - 40 are (x + 10) and (x - 4)
10(x+4)
The greatest common factor of the numbers 40 and 40 is 9.
x2+14x+40 = (x+4)(x+10) when factored
x2-7x-44 (x-11)(x+4)
(x + 10)(x + 4)
x2+14x+40 = (x+4)(x+10) when factored
(x - 5)(x - 8)
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
(x + 10)(x + 4)
You didn't bother to list the binomials to choose from, but the two binomial factors of x2 + 6x - 40 are (x + 10) and (x - 4)
(x2 plus 40) (x minus 1)
First area = (x2 + 14x + 40) sqft; Second area = (x2 +14x + 24) sq ft Difference 16 sqft
