x2-8x+12 = (x-2)(x-6) when factored
one will contain a minus sign and the other will contain a plus sign
Both of the constants must be negative. x2-8x+12 = (x-2)(x-6) That 2 numbers added together equals -8 and when multiplied equals 12 By the way it is not an equation because it is a quadratic expression.
3X + 8You don't factor this as there are no common factors.
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
There are no rational factors.
You don't! There are no common factors.
Write down four brackets with spaces on a piece of paper, ( )( ), like so. factor the first term. In this case the possible factors for the first term is only 2 times 1. Write the factors for the first term in your brackets, (x )(2x ). Determine factors for the second term. In this case the possible factors for the second term are 1 times 30, 2 times 15, 3 times 10, and 5 times 6. Determine the factors and sign for the second term through guess and check. Since the second term in the equation is positive and the third term is negative, one sign must be positive and one must be negative. Through guess and check it can be determined that the correct factor is (x+10)(2x-3). If we check this we get 2x^2-3x+20x-30. Condensed we get 2x^2+17x-30
That factors to (x + 3)(x + 3)
That's 44v + 4 which factors to 4(11v + 1)
5x2 + 3x - 1 does not have rational factors.
x2 + 18x - 50 does not have rational factors.
2(24 + 9) + 2(15 - 8) Remember in Maths ; do inside the brackets first !!!! 2(33) + 2(7) You can either factor '2' or multiply '2' to each set of brackets. Factor ; 2(33 + 7) => 2(40 ) = 80 or Multiply '2' to each set of brackets 2(33) + 2(7) => 66 + 14 = 80 As before. !!!!
