What is the factor of this trinomial x2 plus 13x plus 30?
(x + 10)(x + 3)
Factor the trinomial x2 plus x - 30?
32
How do you factor x2 plus 11x plus 30?
The factors of (x2 + 11x + 30) are (X + 5) and (x + 6)You want to look for two numbers, when multiplied equal 30, and when added equal 11. Start with factors of 30, and see what they add to: 5+6=11, and 5*6=30.
What 2 factors make the sum of -12 and product of 30?
Since 30 is positive and the sum is negative, both factors must be negative. Let's just look for pairs of factors of 30: 30 = 1x30 = 2x15 = 3x10 = 5x6. None of these factor pairs add to 30, so you can't solve this over the integers. You are probably trying to solve a quadratic equation like x2 -12x +30 = 0. Since you can't find two binomial factors for the trinomial, you will have to use the quadratic formula to solve the equation. Haven't got that far in your algebra class? OK, just say it can't be done.
