Question

H/w:- *Factorize* : (by splitting the middle term)

(1) y² - 5y - 14

(2) m² + 5m - 14

(3) x² + 2x - 3​

Answer 1

Step-by-step explanation:

y2-5y-14

y2-7y+2y-14

y(y-7) +2(y-7)

(y+2) (y-7)

Answer 2

Answer:

1) y=7 y= -2

2) m= -7 m=2

3) x=1 x=-3

1) y^2-5y-14

y^2-7y+2y-14

y(y-7)+2(y-7)

(y-7)(y+2)

y=7 y=-2

2) m^2+5m-14

m^2+7m-2m-14

m(m+7)-2(m+7)

(m+7)(m-2)

m=-7 m=2

3) x^2+2x-3

x^2+3x-x-3

x(x+3)-1(x+3)

(x-1)(x+3)

x=1 x=-3

i hope this will help:)
