Question

multiple (7√2-5√3) from (3√2-6√5)​

Answer 1

Answer:

Multiply (√3—√7+2√5) and (√3+√7–2√5)

={√3—(√7–2√5)} x. { √3+(√7–2√5)}.. arranging the terms

=(√3)^2—(√7–2√5)^2..((a--b)(a+b)=a^2—b^2)

=3—((√7)^2–2*√7*2√5+(2√5)^2)..((a -b)^2=a^2–2ab+b^2))

=3—(7+20–4√7*√5)

=3—(27–4√35)

=3–27+4√35

=-24+4√35
