Factor 5x2 plus 14x - 3?
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
How to find two numbers whose sum is 21 and whose product is 90?
Factor 90 and find a combination that would add up to 21. 3x3x5x2. Try 3x3 plus 5x2. Nope. Try 3x5 plus 3x2. 15 + 6 = 21. Got it!
How do you factor 15 plus 5x?
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
How do you factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3) (x + 5).
How do you factor this 2x2 plus 13x plus 15?
2x2+13x+15 = (2x+3)(x+5)
Factor 5x2 plus 14x - 3?
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
What is the factor of 15 plus 45?
The highest common factor of 15 and 45 is 15
How to find two numbers whose sum is 21 and whose product is 90?
Factor 90 and find a combination that would add up to 21. 3x3x5x2. Try 3x3 plus 5x2. Nope. Try 3x5 plus 3x2. 15 + 6 = 21. Got it!
How do you factor 15 plus 5x?
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
What is the gcf of 10y plus 15?
The greatest common factor of 10y plus 15 is 5.
Factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3)(x + 5)
How do you factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3) (x + 5).
How do you factor this 2x2 plus 13x plus 15?
2x2+13x+15 = (2x+3)(x+5)
How do you factor 5x2 -4?
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (0 plus or minus 2 times the square root of 5) divided by 5. x = 0.89442719 x = -0.89442719 If you had an x in there, it would come out nicer. 5x2 + x - 4 = (x + 1)(5x - 4)
Factor x2 plus 18x plus 45?
(x+3)(x+15)
What is the factor of the polynomial expression x3 plus 5x2 plus 3x plus 15?
The factors are : (x² + 3) and (x + 5). Here's how I got that: I plotted it and found it crosses the x-axis at x = -5. Substituting x = -5 verifies that -5 is a root. So one of the factors is (x + 5). Using long division: (x³ + 5x² + 3x + 15)/(x+5) = x² + 3.
Can you factor 5b plus 15?
It is; 5(b+3)
