Question

the value of 'q' if 49p²-q=(7p+½) (7p-½)​

Answer 1

Step-by-step explanation:

$49 {p}^{2} - q = (7p + \frac{1}{2} )(7p - \frac{1}{2} ) \\ 49 {p}^{2} - q = {(7p)}^{2} - { (\frac{1}{2}) }^{2} \\ 49 {p}^{2} - q = 49 {p}^{2} - \frac{1}{4} \\ q = \frac{1}{4}$

Answer 2

Answer:

q= 1/4

Step-by-step explanation:

49p^2 - q = (7p)^2 - (1/2)^2

{ ( a+b)(a-b)=a^2-b^2}

49p^2-q= 49p^2 -1/4

q = 1/4
