Question

the factors of x²+2x-15​

Answer 1

Step-by-step explanation:

${x}^{2} + 2x - 15 \\ {x}^{2} + (5 - 3)x - 15$

${x}^{2} + 5x - 3x - 15 \\ x(x + 5) - 3(x + 5)$

$(x + 5)(x - 3)$

Answer 2

Answer:

(x+5) & (x-3)

Step-by-step explanation:

$x ^{2} + 2x - 15$

$x { }^{2} + 5x - 3x - 15$

$x(x + 5) - 3(x + 5)$

$(x + 5) \: and \: ((x - 3)$
