Question

factories by splitting the middle term
z²+19z-150​

Answer 1

Given equation,

$z^{2} + 19z-150=0$

Solving, we get,

$z^{2} +19z-150=0\\=> z^{2} +25z-6z-150=0\\=>z(z+25)-6(z+25)=0\\=>(z-6)(z+25)=0$

$\boxed{\boxed{\bold{Therefore, \ the\ factors \ are \ (z-6) \ and \ (z+25).}}}$

                                                       

Answer 2

Answer:

Hey mate answer of your question is given below by me...

Step-by-step explanation:

z square+19z-150

By splitting the middle term we obtain.

z square +25z-6z-150

z(z+25) -6 (z+25)

(z-6) (z+25)

(z-6)= 0

z= 6

(z+25)=0

z= -25

I hope it can help you....

Sorry i can not know how can write square.....in phone....
