Question

16x^2 - 64x
factorise the following algebraic expression​

Answer 1

Answer:

16x^2-64x

16x(x-4)

16x=0

x=0

x-4=0

x=4

Answer 2

Step-by-step explanation:

. Factorize the following algebraic expressions:

(i) 64 - x2

Solution:

64 - x2

= (8)2 - x2, since we know 64 = 8 times 8 which is 82

Now by using the formula of a2 - b2 = (a + b)(a – b) to complete the factor fully.

= (8 + x)(8 - x).
