(7x + 8)(7x - 9)
y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
y squared-y-72 is an algebraic expression because it does not contain an equality sign.
350 minus 72 is 278.
8M - 4M - 6 - 3 + 5M = 82 - 1 9M - 9 = 64 - 1 9M - 9 = 63 9M - 9 +9 = 63 + 9 9M = 72 9M/9 = 72/9 M = 8
a2 - a - 72 = (a - 9)(a + 8)

xsquared minus x minus 72
2x^(2) + 72 Factors to 2( x^(2) + 36) s(x^(2) + 6^(2)) Does NOT factor. NB Remember . two squared terms with a positive(+) between them does NOT factor!!!! However, two squared terms with a negative(-) between DOES factor . e.g. x^(2) + 6^(2) Does NOT factor x^(2) - 6^(2) factors to ( x - 6)( x + 6 ) Note the different signs. Similarly 8^(2) + 6^(2) does NOT factor 8^(2) - 6^(2) factors to (8 - 6)(8 + 6) Or using the ~Pythagorean Equation. h^(2) = a^(2) + b^(2) Does NOT factors However, a^(2) = h^(2) - b^(2) factors to a^(2) = (h - b)(h + b) .
