Question

Factorisation by splitting middle term
$(x + a)(x + b) = x {}^{2} + (a + b)x + ab$
1)Factorise x²+4x-45
2)Factorise x²-35x+308​

Answer 1

Step-by-step explanation:

1. x^2 + 4x - 45

x^2 + 9x - 5x - 45

x(x+9) - 5(x+9)

(x+9)(x-5)

2. x^2 - 35x +308 (i think this question is wrong in place of 35 there should be 36)

x^2 - 14 x - 22x + 308

x(x-14) - 22(x-14)

(x-14)(x-22)

Answer 2

Answer:

1) (x+9) (x-5)
