​

Answer 1

Step-by-step explanation:

${x}^{2} - 3x - 10 \\ \\ \frac{ - b + \: or \: - \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ \frac{3 + \: or \: - \sqrt{9 + 40} }{2(1)} \\ \frac{3 + 7}{2} \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \frac{3 - 7}{2} \\ 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: - 2$

Answer 2

Step-by-step explanation:

by factorization: (i) x2 – 3x – 10 = 0 x2 – 3x – 10 = 0 We factorize using splitting the middle term method x2 + 2x – 5x
