Step-by-step explanation:
-5x = 10 + 10
-5x = 20
X = 20/-5
X = -4
check :
-5 x -4 =20
20 =20
All you need to do is multiply the two together
12 times 16 = 192 copies
Answer:
ans: -4( x-3 )( x-4 ) I.e -4( x² + x - 12 )
Step-by-step explanation:
as per question
1- (2x-7)²
= (1 + 2x - 7)(1- 2x + 7)
= ( 2x - 6)(-2x +8)
= -4(x-3)(x+4)
