Which of the binomials below is a factor of this trinomial?15х2 + 13х- 20А. 3x+5В. 3x-4с. 3х - 5D. 3х + 4
Accepted Solution
A:
Answer:A. 3x+5Step-by-step explanation:To factor this equation, i will factor by grouping(15x²-12x) + (25x - 20)Then ill factor a 3x from (15x²-12x)3x(5x-4x)and factor a 5 from (25x - 20)5(5x - 4)So the equation can be written as:3x(5x-4x) + 5(5x - 4)if we factor a 5x-4 from both terms, the equation is(5x-4)(3x+5)So 3x + 5 is your answer.
