Hello friend, I’ve done few steps for 1st expression, but I can’t solve any further. Can u pls help?
= m3 - 8n3
= m3 - (2n)3
= (m - 2n)(m2 + 2mn + 4n2)
= (m - 2n)... ??
I am stuck in first expression. I'm not sure how to solve further. Pls help
1st expression = 8x3 + 4x2 + 2x
= 2x(4x2 + 2x + 1)
How can I solve this? The 45-A is making me so confused. Plz help
Can someone pls help me to solve this? I just know that sin2A = 2sinA.cosA, but it doesn't seem like that formula is helpful in this question. I have no idea about what to do for sin3A.
Can someone please help me to solve this question?
I can't go beyond this:
= cos⁴A + sin⁴A
= (cos2A)2 + (sin2A)2
I can't solve it after this :(
