yes
What is the factored form of 15x plus 32x -28?
15x + 32x - 28 = 47x - 28 = (√47x)2 - (√28)2 = (√47x)2 - (2√7)2 = (√47x - 2√7)(√47x + 2√7)

How do you solve 6x plus 18 plus 9x-25?
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
How factor 6x -15x -21?
I think you mean 6x2-15x-21 2x2-5x-7 2x2-7x+2x-7 x(2x-7)+1(2x-7) (x+1)(2x-7)
How do you solve 15x(7-7) (5x2)?
To solve the expression (15x(7-7)(5 \times 2)), first simplify the term inside the parentheses: (7 - 7 = 0). This means the entire expression becomes (15x \times 0 \times (5 \times 2)). Since any number multiplied by zero is zero, the final result is (0).
What is the answer to 9x plus 7 equals 15x plus 1 and how do you find it?
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
What is the factorization of the polynomial of x2 - 15x - 56?
This will only give a rational answer when it's +56. Then you're looking for two numbers that add to 15 and multiply to 56. That's 7 and 8. If it's -15x, the answer is (x - 8)(x - 7) If it's +15x, the answer is (x + 8)(x + 7)
What 5x 3x-7 and 12x 12?
To simplify the expression (5x(3x - 7) + 12x(12)), first distribute (5x) and (12x): (5x(3x - 7) = 15x^2 - 35x) (12x(12) = 144x) Now, combine like terms: [ 15x^2 - 35x + 144x = 15x^2 + 109x ] Thus, the simplified expression is (15x^2 + 109x).
