Question

x2 + 3x -p -7p - 10 factor​

Answer 1

Answer:

Factors are (x-2) and (x+5)

Step-by-step explanation:

You may find the factor of

${x}^{2} + 3x - 10 = 0$

So to factorise this,split the middle term ,so that multiplication of those terms gives us

$- 10 {x}^{2}$

So

${x}^{2} + 5x - 2x - 10 = 0 \\ \\ x(x + 5) - 2(x + 5) = 0 \\ \\ (x - 2)(x + 5) = 0 \\ \\ x - 2 = 0 \\ \\ x = 2 \\ \\ or \\ \\ (x + 5) = 0 \\ \\ x = - 5$

So factors are (x-2) and (x+5)
