Question

x² + 2 x - 63 in breaking the middle term​

Answer 1

Answer:

Here's the Answer!!

Step-by-step explanation:

x2 + 2 x -63=0

(-63 is factor of 9 *7)

Therefore,

x2+ 9x - 7x -63=0

x( x+9) -7( x+9) =0

So,

(x+9)(x-7)=0

Therefore,

(x+9)=0

x=( -9)

(x-7)=0

x= 7

Thus, values are ( -9) & 7.
