Factor 2x squared plus 6x - 8 equals 72?
2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i

How do you factor 2x2-72?
2x^(2) - 72 Factor out '2' Hence 2( x^(2) - 36) => ( Recognise that '36' is a squared number ; 6^(2) ) . 2(x^(2) - 6^(2)) NB Two squared terms with a NEGATIVE (-) will factor. Hence 2(x - 6)(x + 6) NB Note the different signs in the brackets. NNB A positive (+) between two squared terms does NOT factor.

How would you factor 2x squared plus 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) .
