4x to the 3rd power -4x to the 2nd power -43 when x=3
What is -5(3x 6)-3(4x-2)?
-66.
What is -3x - -4x in factored form?
- 3X - (- 4X) is the same as - 3X + 4X X(- 3 + 4) that is all the factoring needed there
What is 2x divided by 3 equals x divided by 2 plus 20?
2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
How do you factor the polynomial 12x2-5x-2?
Assuming you mean 12x2 - 5x - 2, use the reverse FOIL method. But, first, multiply the two end number together (12 * -2 = -24). Then find two numbers whose product is -24 and sum is -5. These two numbers are 3 and -8.3 * ( -8 ) = -24 and 3x + ( -8x ) = -5xNext, we use those factors found in the previous step and group them together.12x2 - 5x - 212x2 + 3x - 8x -2( 12x2 + 3x ) ( -8x - 2 )Next, take out the common factors from each group( 12x2 + 3x ) ( -8x - 2 )3x ( 4x + 1 ) - 2 ( 4x + 1 )Lastly, group the two ungrouped terms multiplied by their common factor ( 4x + 1 )3x ( 4x + 1 ) - 2 ( 4x + 1 )( 3x - 2 ) ( 4x + 1 )Next, we check the work by usingthe FOIL method.( 3x - 2 ) ( 4x + 1 )F ... 3x * 4x = 12x2O ... 3x * 1 = 3xI ... -2 * 4x = -8xL ... -2 * 1 = -212x2 + 3x - 8x - 2Combine like terms12x2 - 5x - 2
